The Venus Transit across the Sun event on June 5-6 will not be seen again for 105 years – How to watch Online

 

The June 8, 2004, transit of Venus photographed by Frans Snik at the Dutch Open Telescope in La Palma, Canary Islands.

 

Transits of Venus are very rare, coming in pairs separated by more than a hundred years. This June’s transit, the bookend of a 2004-2012 pair, won’t be repeated until the year 2117. Fortunately, the event is widely visible. on seven continents, even a sliver of , will be in position to see it.

The nearly 7-hour transit begins at 3:09 pm Pacific Daylight Time (22:09 UT) on June 5th. The timing favors observers in the mid-Pacific where the sun is high overhead during the crossing.  In the USA, the transit will at its best around sunset. That’s good, too. Creative photographers will have a field day imaging the swollen red sun “punctured” by the circular disk of Venus.

Observing tip: Do not stare at the sun. Venus covers too little of the solar disk to block the blinding glare.  Instead, use some type of projection technique or a solar filter. A #14 welder’s glass is a good choice.  Many astronomy clubs will have solar telescopes set up to observe the event; contact your local club for details.

Transits of Venus first gained worldwide attention in the 18th century.  In those days, the size of the solar system was one of the biggest mysteries of science.   The relative spacing of planets was known, but not their absolute distances. How many miles would you have to travel to reach another world?  The answer was as mysterious then as the nature of dark energy is now.

Venus was the key, according to astronomer Sir Edmund Halley. He realized that by observing transits from widely-spaced locations on Earth it should be possible to triangulate the distance to Venus using the principles of parallax.

The idea galvanized scientists who set off on expeditions around the world to view a pair of transits in the 1760s.  The great explorer James Cook himself was dispatched to observe one from Tahiti, a place as alien to 18th-century Europeans as the Moon or Mars might seem to us now.  Some historians have called the international effort the “the Apollo program of the 18th century.”

In retrospect, the experiment falls into the category of things that sound better than they actually are.  Bad weather, primitive optics, and the natural “fuzziness” of Venus’s atmosphere prevented those early observers from gathering the data they needed.  Proper timing of a transit would have to wait for the invention of photography in the century after Cook’s voyage.  In the late 1800s, astronomers armed with cameras finally measured the size of the Solar System as Edmund Halley had suggested.

This year’s transit is the second of an 8-year pair. Anticipation was high in June 2004 as Venus approached the sun.  No one alive at the time had seen a Transit of Venus with their own eyes, and the hand-drawn sketches and grainy photos of previous centuries scarcely prepared them for what was about to happen.  Modern solar telescopes captured unprecedented view of Venus’s atmosphere backlit by solar fire.  They saw Venus transiting the sun’s ghostly corona, and gliding past magnetic filaments big enough to swallow the planet whole.  One photographer even caught a spaceship, the International Space Station, transiting the alongside .

2012 should be even better as cameras and solar telescopes have improved. Moreover, NASA’s Solar Dynamics Observatory is going to be watching too. SDO will produce Hubble-quality images of this rare event.

The occasion also celebrates the first while there is a orbiting the planet – ESA’s Venus Express.

ESA will be reporting live from the Arctic island of Spitsbergen, where the Venus Express science team will be discussing the latest scientific results from the mission while enjoying a unique view of the 2012 transit under the ’midnight ’.

A transit of Venus occurs only when Venus passes directly between the Sun and Earth. Since the orbital plane of Venus is not exactly aligned with that of Earth, transits occur very rarely, in pairs eight years apart but separated by more than a century.

The last transit was enjoyed in June 2004 but the next will not be seen until 2117.

Venus transits are of great historical significance because they gave astronomers a way to measure the size of the Solar System.

The transits of the 18th century enabled astronomers to calculate the distance to the Sun by timing how long it took for Venus to cross the solar disc from different locations on Earth and then using simple trigonometry.

Also, during the transit of 1761 astronomers noticed a halo of light around the planet’s dark edge, revealing Venus to have an atmosphere.

Thanks to spacecraft that have since visited Venus, including Venus Express, we now know that it hosts an inhospitable dense atmosphere of carbon dioxide and nitrogen with clouds of sulphuric acid.

Today transit events are a valuable tool for developing methods for detecting and characterising planets orbiting other stars than the Sun, planets that astronomers refer to as exoplanets.

As a planet passes in front of a star, it temporarily blocks out a tiny portion of the starlight, revealing its presence and providing information about the planet’s size. Europe’s CoRot space telescope has used this technique to discover over 20 exoplanets.

Transits are also being used to search for exoplanets that may harbor life. If the planet has an atmosphere a small fraction of the light from the star will pass through this atmosphere and reveal its properties, such as the presence of water or methane.

During next month’s transit, astronomers will have the chance to test these techniques and add to the data collected during only six previous Venus transits observed since the invention of the telescope in the early 1600s.

The 2012 transit will be visible in its entirety only from the western Pacific, eastern Asia, eastern Australia and high northern latitudes.

For the US, the transit will begin in the afternoon of 5 June and for much of Europe the Sun will rise on 6 June with the transit almost finished. If you are observing the event please remember – NEVER look at the Sun with unprotected eyes, through ordinary sunglasses or through a telescope, as this will cause permanent blindness.

The Sun does not set at Spitsbergen in June, providing a unique opportunity to observe the entire transit from 22:04 GMT 5 June (00:04 CEST 6 June) to 04:52 GMT (06:52 CEST).

“We’re very excited about watching the transit from such a unique European location while Venus Express is in orbit around the transiting planet,” says Håkan Svedhem, ESA’s Venus Express project scientist.

“During the transit, Venus Express will make important observations of Venus’ atmosphere that will be compared with ground-based telescopes to help exoplanet hunters test their techniques.”

Astronomers are gearing for one the rarest events in the Solar System: an alignment of Earth, Venus and the Sun that will not be seen for another 105 years.

The celestial ballet known as the Transit of Venus is one of the most eagerly-awaited events in skywatching, an episode that has advanced the frontiers of knowledge, sometimes with dramatic consequences.

“For centuries, the Transit of Venus has been one of the great moments for astronomers,” said Claude Catala, head of the . “2012 will not be an exception to the rule. It is a one-off opportunity.”

“It’s now or never,” the British magazine Physics World told its readers.

“It will be an event well worth watching, as the next Transit of Venus will not occur until December 2117, when most of us will be long gone.”

In a transit, Venus passes between Earth and the Sun, appearing through the telescope as a tiny black spot that, for some six and a half hours, crawls in a line over the fiery face of the Sun.

On the evening of June 5, North America, Central America and the northern part of South America will get to see the start of the transit — clear skies permitting — until those regions go into sunset.

All of the transit will be visible in and the Western Pacific.

Europe, the Middle East and will get to see the end stages of the eclipse as they go into sunrise on June 6.

But West and Southwest Africa, and most of South America, will not get a view, although people there can catch the event on a webcast.

Only six Transits of Venus have ever been recorded — quite simply because before the phenomenon was predicted by the 17th-century German mathematician , no-one knew where to look or had the lenses to do so.

Description of the June 5-6 transit of Venus across the Sun. Astronomers are gearing for one the rarest events in the Solar System: an alignment of Earth, Venus and the Sun that will not be seen for another 105 years.

Transits occur in truly weird combinations, either in a June or a December. When one happens, another one happens in the same month eight years later.

Then there is a wait.

A very long wait.

A pair of December transits follows a June pair after 105 years, while a June pair comes 121 and a half years after a December pair.

For example, there was a transit in December 1882; the next one was in June 2004, which will be followed this year on June 5-6, depending on the dateline; astronomers will then have to be patient until December 2117, which will be followed by another transit in December 2125.

In the 18th century, scientists realised that by timing the event from different locations, the transits of 1761 and 1769 could be triangulated and give the distance between Earth and the Sun — “the noblest problem in astronomy,” for it would at last place mankind in the cosmos.

Britain and France, the two superpowers at the time, jockeyed for the glory, dispatching missions to far-flung places.

Among them were British surveyors Charles Mason and Jeremiah Dixon, who were attacked by French warships just after they left Plymouth and headed back to port.

Discouraged, they wanted to cancel the trip — but ventured back out to sea after a receiving a now-legendary letter from the Royal Society, the British scientific academy which was sponsoring them.

To give up would “bring an indelible Scandal upon their Character, and probably end in their utter Ruin,” the letter said stonily.

Drama was also in store for the 1769 transit, when Britain sent James Cook to Tahiti to view the event from there.

After his mission, Cook opened the instructions for the secret — and most important — part of his expedition: to search for and map for the Crown a mysterious “southern continent,” which turned out to be New Zealand and eastern Australia.

For astronomers today, the Transit of Venus offers a chance to gain insights into the planet’s notoriously thick, cloudy atmosphere, and use the refraction of sunlight to finetune techniques for hunting planets orbiting distant stars.

One of the most useful exercises will be to compare observations of the transit made by Earth-based telescopes, orbitaltelescopes and robot probes, including Europe’s Express.

“This way we get different measurements with which to calibrate our methods for analysing exoplanets orbiting other stars,” said Thomas Widemann, of the Laboration of Space Studies and Astrophysics Instrumentation, or LESIA, in Paris.

SAFETY FIRST: Proper solar filters are a must for viewing the , to avoid damage to the eyes.

“The of across the face of the is one of the rarest events in the . Venus has passed directly between the Earth and sun only 52 times between 2000 BC and 2000 AD; that’s 4,000 years! There have only been seven Venus transits since the invention of the telescope in the early 1600s. The transit on June 5 will be No. 8. The next chance to see a Venus transit is in 105.5 years.

“Based on his careful calculations, Johannes Kepler was the first scientist to predict that Venus would pass across the face of the sun, and the first observed transit was in 1639.

“During a transit, Venus appears as a large black dot moving slowly across the solar disk. At the start of the transit of 1761, a ring of light was seen around the disk of Venus and it was realized that the planet Venus must have an atmosphere. Today, astronomers are using the same technique to study the atmospheres of extrasolar planets that directly pass between us and their star. NASA’s Kepler mission is a dedicated space telescope that searches for planets transiting distant stars. While we have a close-up view of Venus, the distant transits show up as a very small fading of a star’s light. The Kepler mission has discovered hundreds of planets using the transit technique.

“Why is the alignment of Venus and the sun so rare? The orbit of the Earth defines a plane called the ecliptic, and the orbit of Venus is inclined to the ecliptic plane by 3.8 degrees. Since the face of the sun appears only a half-degree across as seen from the Earth, Venus usually misses the solar disk either passing just below or above the sun. Only when Earth and Venus are both near the line where their orbital planes meet can a transit occur.

“Kepler’s math defined the relative orbits of the planets very accurately, but the size of the solar system remained uncertain. Even the distance between the Earth and the sun, called the ‘,’ was poorly known in the 18th and 19th centuries. Sir Edmond Halley (of Halley’s comet fame) and others realized that the transit of Venus provided an opportunity to directly measure the astronomical unit and set the scale of the solar system. By sending out observers around the world to make accurate timing of the start and end of a transit of Venus, the distance to the sun could be measured geometrically.

“The true size of the solar system was the most important cosmological question for over 200 years. Just as measuring the expansion rate of the universe, the Hubble constant, occupied astronomers for the past 80 years, the length of the astronomical unit was the fundamental problem of the 1700s and 1800s. Expeditions to observe the Venus transits of 1761 and 1769 were sent around the world but failed to achieve the timing accuracy needed for a good measurement of the astronomical unit. But expeditions to the transits of 1874 and 1882 allowed the astronomical unit to be measured to an accuracy of 0.2 percent.

“The transits of 2004 and 2012 are not scientifically critical for setting the size of the solar system. Using satellites and radar, we now know the distance between the Earth and sun to better than the length of a football field.

“At the time of the Venus transit of 1882, there were eight known planets, all in orbit around the sun. For the Venus transit of 2012, there are over 700 cataloged planets, many discovered by their transit across the face of their stars by the Kepler satellite. None of these new extrasolar planets are as small or as Earth-like as Venus. But as we watch this latest transit of Venus, we can imagine on another world across the galaxy, excited extraterrestrial astronomers watching a double transit of two small planets temporarily dim the light of an ordinary star.”

Garnavich was awarded a share of the 2007 Gruber Prize in Cosmology for his work in the High-Z Supernova Search team’s discovery of the accelerating universe. He also is co-investigator on the largest Hubble project ever undertaken, one that will watch galaxies form and hunt for distant explosions.

In 1761, Harvard’s Hollis Professor of Mathematics and Philosophy John Winthrop loaded a grandfather clock and a couple of students into a boat and embarked on Harvard’s first astronomical expedition.

They set out on the provincial sloop, under orders from Massachusetts Bay Gov. Francis Bernard to convey them to Newfoundland, North America’s easternmost settlement, so that Winthrop could view one of nature’s rarest astronomical phenomena: ’ passage across the face of the sun.

Called a “transit of Venus,” the event is an eclipse of the sun by Venus. In this case, however, Venus appears as a black dot that tracks a line across the sun’s face for several hours. On June 5 of this year, skywatchers around the world will watch the sun to catch a glimpse of the same event, which remains a curiosity for many, even if it has lost much of the scientific importance it bore when Winthrop voyaged to Newfoundland.

“As an amateur astronomer as a kid I read about this thing that was so far in the future,” said Owen Gingerich, professor of astronomy and of the history of science emeritus. “I thought, wouldn’t it be neat to see something so rare?”

Transits of Venus occur in pairs, eight years apart, separated by more than a century. Winthrop’s transit in 1761 was followed by one in 1769. The next pair occurred in 1874 and 1882, and the most recent was in 2004. The next transit after this month’s won’t occur until 2117.

Gingerich traveled to Sicily with his wife to view the 2004 transit because it could be viewed in its entirety in Europe. This year, Gingerich is traveling to California to view it. Here at Harvard, the Harvard-Smithsonian Center for Astrophysics (CfA) is holding an event at 6 p.m. on June 5 to view the first part of the transit, which will begin just before sunset. The Arnold Arboretum is also marking the occasion on May 30, with a talk by historian Andrea Wulf on her book about the 1761 and 1769 transits.

The 2004 transit had some scientific merit and was used to test techniques to find planets circling other stars. But the earlier transits were international scientific events. In particular, the transits in the 1700s generated an enormous amount of interest because, if observed carefully, the passage of Venus across the sun could be used to determine the then-unknown size of the solar system.

“This would give us a just idea of the vast dimension of the solar system and the mighty globes which compose it,” Winthrop wrote in his account of the Newfoundland expedition, “Relation of a Voyage from Boston to Newfoundland for the Observation of the Transit of Venus.”

Before the 1761 transit, the event had been observed only in 1639. In the intervening years, Edmond Halley had proposed a way to determine the distance from the Earth to the sun using measurements of the transit of Venus from two distant places on Earth. A key factor in the calculations was the difference in the time it took Venus to cross the sun’s surface, as viewed at the two locations.

Halley died before the 1761 transit, but his exhortations to his scientific colleagues were heeded.

“From a sense of the advantages to be derived from this observation, Dr. Halley recommended it in the most emphatical terms, and inforced it with all the energy of language, on the Astronomers and others of the present day, that they would by no means let slip an opportunity,” Winthrop wrote. “And to put the matter beyond all hazard, he advised to have a number of Observators stationed in different parts of the Earth, that some of them might be sure to succeed; as a single person might be frustrated by the intervention of clouds.”

That 1761 transit was invisible to most of North America, because it occurred before sunup over large swaths of the land. Winthrop’s trip to Newfoundland was spurred by his desire to see the last part of it, visible only from the continent’s easternmost part.

Winthrop’s account details landing at St. John and searching for a suitable home where his group could set up, only to be stymied by hills to the east. They ultimately hiked over the hills and set up tents to wait for the event, amid an unrelenting horde of insects that “persecuted us severely, without intermission, both day and night, with their venomous stings.” Because accurate timekeeping was of the essence, they brought a large grandfather clock from Harvard — on display today in the Science Center’s Putnam Gallery — which they fixed to a post driven into the ground, and set to wait.

“Thus prepared, we waited for the critical hour, which proved favorable to our wishes,” Winthrop wrote. “The morning of the 6th of June was serene and calm. The sun rose behind a cloud that lay along the horizon but soon got above it; and at 4h 18m [4:18 a.m.] we had the high satisfaction of seeing that most agreeable sight, Venus on the Sun.”

Winthrop took his measurements, sharing the view with “gentlemen of the place, who had assembled very early on the hill to behold so curious a spectacle.”

Science would be stymied, however, by the inexactness of the instruments of the day. The global scramble would be repeated in 1769 by a group that included, among others, Capt. James Cook, who voyaged to Tahiti to view the transit. A 1771 estimate of the distance from the Earth to the employing multiple measurements from both transits came in not too badly, at 95 million miles. The estimates would be refined to very close to the known value of 93 million miles a century later, after the 1874 and 1882 transits, the latter of which was observed at Harvard by a group of astronomers led by Observatory Director Edward Pickering.

How to Watch

On Tuesday, June 5, skywatchers in North America will have their last chance to see Venus pass in front of the sun for over a century. Because of the International Date Line, this event will occur on Wednesday June 6 in Asia, Australia, Africa, and Europe.

This event, called a transit of Venus, is one of the rarest sights in astronomy. Transits of Venus occur in pairs 8 years apart, each pair separated from the next by over a century. The last pair occurred in 1881 and 1889, and the next pair will occur in 2117 and 2125. This week’s transit is paired with a transit which occurred on June 8, 2004.

Why are transits of Venus so rare?

As the graphic associated with this guide shows, Venus’ orbit is tilted by 3.4 degrees as compared to the Earth’s orbit. As a result, most of the time Venus passes either above or below the sun when Venus is inferior conjunction with the sun (between the sun and Earth). Only when both Venus and Earth are at the points where the two orbits cross can we see Venus in front of the sun. [2004 Venus Transit: 51 Amazing Photos]

Venus transit observing safety

WARNING: It is always dangerous to stare directly at the sun!The sun’s heat, when concentrated by your eye’s lens on your eye’s retina, can literally cook your sensitive retinal cells. The result can be a permanent blind spot in your eye. You only get one pair of eyes, so don’t risk permanently damaging them.

There are only two safe ways to observe the transit of Venus

One way is to block the sun’s damaging rays with a dense filter. The only safe filters are a #14 welder’s glass, sold only by specialized welder’s supply stores, or “eclipse shades”: special glasses available only from telescope stores and astronomy clubs. Either of these cost less than a couple of dollars, so there’s no excuse to endanger your eyes.

The only other safe way to observe the sun is with a “pinhole camera.”

This can be made from a large cardboard box, such as a mover’s “two-cube.” Make a small hole in one end of the box, about a millimeter or two in diameter, which acts as the “lens,” and place a white sheet of paper in the opposite end to serve as the viewing screen. Place the box over your head resting on your shoulders, and watch the transit on the screen. [Video: How to Make a Pinhole Camera]

Much simpler pinhole cameras can be improvised from any object with a small hole, but the advantage of using a large box is that it keeps stray light off the screen, allowing you to use a smaller pinhole, for a sharper image.

If you’re observing with binoculars or a small telescope, there is no substitute for a proper full-aperture solar filter. Unless you block the sunlight from entering the telescope, you run the risk of concentrating the sun’s light.

It was once common for solar observers to use their telescopes to project an image of the sun with an eyepiece. That was in the days when telescopes were made of metal and glass. Nowadays there is much plastic, and even cardboard, used in making telescopes and eyepieces, so that you run the risk of “meltdown” or even fire. It’s just not safe.

So, when is the best time to observe the transit?

In North America the best time will be in the hours before sunset on Tuesday afternoon. In Europe, Africa, and Australia, Venus will be in transit as the sun rises on Wednesday morning (June 6). In most of Asia and across the Pacific Ocean, any time during Wednesday should work. Detailed times are shown in the table accompanying this guide.

Astronomers chronicle Venus transits in terms of “contact.” First contact is when Venus first touches the outer edge of the sun. Second contact is when Venus is first entirely on the sun. Similarly, third contact is when Venus touches the sun’s edge from the inside, and fourth contact is when it is totally off the sun.

This chart shows the times of “contact” between Venus and the sun during the transit of Venus for major cities on June 5, 2012. CREDIT: Starry Night Software 

What will you see?

For most observers, Venus will be a tiny round black disk, but large enough to be clearly visible with the unaided eye, properly protected by eclipse glasses or welder’s glass. If you’re viewing with a telescope, the most interesting times will be as Venus is entering or leaving the sun’s disk.

One of the things to look for is the so-called “black drop” effect.

Here’s an example: Hold up your thumb and forefinger in front of a bright background so that they are almost touching. You will see an interesting optical illusion whereby a black ligament appears to bridge the gap.

For the Venus transit, a similar illusion occurs just after second contact and just before third contact, when a dark ligament appears to join Venus to the dark sky. But is this entirely an optical illusion? Remember that Venus has a dense atmosphere which could contribute to this effect.

Many observers have reported seeing Venus as a bright ring just before it enters the sun’s disk and just after it leaves. Mikhail Lomonosov, who organized the observations of the transits in the 1760s, correctly deduced from this that Venus had an atmosphere, illuminated from behind by the sun.

One difference between this transit and the one eight years ago is that many amateur astronomers now have telescopes which allow them to view the sun in hydrogen alpha light. It should be possible to see Venus silhouetted against prominences and the corona, before it moves in front of the chromosphere.

These are just a few of the interesting things which may be visible next Tuesday (or Wednesday, depending on your location).

How to Watch Online

Much of the world will be able to witness a rare skywatching event on June 5, as Venus crosses the face of the sun in a spectacle that will not be visible again for more than a century. But for anyone who is not able to see the so-called transit of Venus in person, there are other ways to catch the historic event online.

While observers in many parts of the world — including North America, Europe, Asia and eastern Africa — will be well-placed to see at least part of the transit in person, several organizations are planning to broadcast live views using footage from various observatories and telescopes around the globe.

Since the event occurs across the International Date Line, the transit of Venus will occur on Wednesday June 6 in Asia, Australia, Africa, and Europe.

The reason for the wide interest in the Venus transit is clear: This is the last time anyone alive today will have a chance to see Venus cross the face of the sun. The next transit of Venus won’t occur until the year 2117. Venus transits occur in pairs eight years apart. The last one occurred in 2004, making the 2012 transit the last in the current series.

Viewers who decide to tune into a webcast will be able to watch the entire transit unfold, as Venus appears to touch the outer edge of the sun, then travels onto the face, before crossing the inside edge and continuing along its orbit.

NASA will be hosting a Sun-Earth Day webcast on June 5 that will last the entire length of the Venus transit. The footage will stream live from the summit of Mauna Kea, Hawaii, with accompanying commentary from various experts. Times are subject to change, but the webcast is currently scheduled to begin at 5:45 p.m. EDT (2145 GMT). [Transit of Venus 2012: An Observer’s Guide]

People can tune in to NASA’s Venus transit broadcast by visiting the agency’s Sun-Earth Day website: http://sunearthday.gsfc.nasa.gov/webcasts/nasaedge/

The Slooh Space Camera will stream ten real-time feeds of the transit from solar telescopes in Australia, Japan, New Zealand, Hawaii, Norway, Arizona and New Mexico. The webcast, which begins on June 5 at 6 p.m. EDT (2200 GMT), will track Venus’ entire journey across the sun.

The show will also feature commentary from astronomers, filmmakers, science writers, engineers and solar experts.

“A few odd phenomena happen during Venus transits, like the ‘black drop’ that seems to connect the planet with the space outside the sun, which will be highlighted and discussed by our experts as it happens,” said astronomer Bob Berman, who will be one of the guests during Slooh’s webcast.

Viewers can access this webcast by visiting Slooh’s homepage on June 5: http://events.slooh.com/

Another option is the webcast hosted by San Francisco’s Exploratorium. The museum will showcase a 6.5-hour live event with telescope feeds from the Mauna Loa Observatory in Hawaii. This footage will be accompanied by audio commentary every 30 minutes, according to officials at the Exploratorium.

The Exploratorium webcast will begin at 6:09 p.m. EDT (2210 GMT) and last until 12:49 a.m. EDT June 6 (0445 GMT June 6).

People are invited to watch the webcast on large screens at the museum (during museum hours), or online at http://www.exploratorium.edu/venus.

Astronomers Without Borders will also be broadcasting the transit live from the Mount Wilson Observatory near Pasadena, Calif., where astronomer Edwin Hubble worked to explain the expanding universe and the nature of galaxies.

 

The webcast will include interviews with experts and amateur astronomers. Members of the Antique Telescope Society will use vintage telescopes to observe the transit, just as predecessors in the 18th and 19th centuries did.

More information on the webcast, plus how to view it, is available on the Astronomers Without Borders homepage: http://www.astronomerswithoutborders.org/projects/transit-of-venus/live-webcast.html

WARNING: For skywatchers who are planning to view the transit of Venus in person, it is important to exercise caution. It is very dangerous to stare directly at the sun. Special eclipse glasses and filters for telescopes are needed to avoid permanently damaging your eyes.

  1. I am a fully qualified ecaetricll Technician and Computer Tech.With a lot of experience with Transmitters/receivers.I watched a program on the T.V which was showing how they were/are going to switch more ecaetricll power lines on to help absorb the MAGNETIC effect which will generate electricity in all most every cable and coil in the U.K.How will this help as the Transformers will go into melt down and the grid will be self generating with each magnetic wave which passes through any cable (conductor). making the wiring system act as generating its own electricity ( Check out The Carrington Effect ).The telegraph system suffered with huge amounts of self generated ecaetricll induced in there cables.The only sure way is to earth all the grid to the ground .and the Transformers.I was in Quebec when the last big solar storm in about 1995 approx burnt out HUGE TRANSFORMERS worth millions of dollars. Simple Rule to use if you wish to keep those Electronics devices which will be of great value to keep your vehicle on the road is buy a replacement vehicle management system ,Alternator,distributor parts .battery.light bulbs.possibly starter motor.Drive earthing rods into the ground around your vehicle and earth your vehicle to the earthing rods.The spair parts for your car put in a well insulated water tight container and wrap with metal foil on the outside of the insulated container ,Then bury the parts and any thing else you wish to keep,eg working Communication Equipment radio,c.b.lights, bulbs,If you can get a generator be for this solar flare and make the same insulated box around it and put /cover the outside of box with metal .it will be handy to have a siphoning set to siphon Fuel from were ever you can barter for it as no banking system will work and no ATM .no credit cards will be working as no phones even if they are OPTICAL lines .Last but not least protect what you need .FOOD STOCKS >FUEL>WATER>.Water purifying tablets .Do not think that any emergency services will be able to help or you will get your pay for working NO BANKS=NO WORK.

They are my own words, copied word by word by an email message that I sent out to a newsletter group of which he was a recipient of. I find it in poor taste for him to take my words as his own.My original statement:Greetings!!We have good news!! North Bay event details have been confirmed for June 6th 2012 at Namaste Energy Center. This is a very special time as we will be exploring the significance of the rare Venus Transit of June 5/6 2012, which only happens every 120 years (approx) and in pairs of 8 years apart. The first transit of this pair was on June 8, 2004. The evolution of humanity advanced exponentially during the previous transits of Venus. 2012 s completion of this transit pair will see the return of the Divine Feminine, propelling us to new heights of spiritual evolution.I hope you will join us for the very special event in North Bay. Details are below and a poster is attached for easy sharing. Please forward to friends and place a copy on a bulletin board near you as I am only arriving in North Bay in the early afternoon of the 6th.
