Swift Mercury Zips Across the Sun's Disc
Skywatchers and Stargazers are preparing for a rare solar system event:
On November 8, 2006, at 2:12 PM EST and 11:12 AM PST, in less than 5 hours, speedy Mercury zips across the Solar Disc. (West of the International Date Line: November 9, 2006)
What is a "Transit of Mercury"? Simply, it is a very special kind of eclipse. Aside from the more common Lunar Eclipse and Solar Eclipse once in a rare while, a planet travels directly between the Earth and the Sun. This is called a Transit and happens only with Mercury, rarely, and Venus, even more rarely. You may recall the June 8, 2004 Transit of Venus (Next one: June 5-6, 2012). Weather permitting, and with proper viewing devices (Always protect your eyes from the Sun! See below or Click here for NASA Safe Viewing Techniques.) we can see Mercury as small black dot moving across the disc of the Sun.
Astronomers and Observatories from Australia to Japan to the Western US will be gearing up for Live Online Webcam Viewing (See links below).
Best Viewing- (Full Daylight) The South Pacific (Western Australia, New Zealand, Pacifica/ Polynesia, Hawaii, Western North America: most of Alaska, and the Western edge of the Continental US, and Mexico, and Antarctica.
Partial Viewing- (Sunrise) China, Japan, Southeast Asia, Indonesia, New Guinea to Western Australia. (Sunset) Most of North & South America.
(See Map Links below.)
This is a rare and special event- don't miss it!

The real transit took about 5 1/2 hours
Eye Safety: NEVER LOOK DIRECTLY AT THE SUN!
Especially with magnifying optical devices: binoculars, telescopes, etc.
Night time sky watching may be done safely with the the naked eye. The brightest natural object will be a full moon.Daytime viewing is quite different, however. The Sun, is a very different case. Never, never, NEVER look directly at the Sun without proper filtering!!! Seriously, you can do major permanent damage to the retina.
Unless you have special solar filters, optical devices such as BINOCULARS AND TELESCOPES WILL NOT PROTECT YOUR EYES. Because of their magnifying effect, viewing the sun through these without proper filtering can cause more damamge than directly gazing at the sun. Most telescopes will utilize a solar projection screen for safe viewing of the sun.
The safest, most widely available "live viewing" is an online webcam, of course. If you must have the "direct experience" please check with the experts so that you will be able to enjoy viewing many celestial phenomena for years to come.

The Transit of Mercury Webcast hosted by the NASA Digital Learning Network. From their home page just choose the Transit of Mercury feature.
NASA Digital Learning Network
Specific Webcast information on the DLN
Webcast Air Time:
Start: 1:30 ET
End: 2:30 ET
Webcast Content:
During the webcast we will feature:
A panel of scientists live from NASAs Goddard Space Flight Center with an additional panel of educators and amateur astronomer live from Langley Research Center.
2 NASA Explorer Schools will be connected for live interaction-questions and answers.
A telescope 'safety viewing' demonstration with instructions on how to view the transit using a classroom solarscope.
Live images of the transit from 2 NASA satellites, SOHO and TRACE.
Live ground based images from Kitt Peak and Hawaii!
Note from SOHO:
LASCO C3 will begin seeing Mercury in its field of view beginning on Nov. 5. It will be pretty bright. It disappears from our view on Nov. 12. Incidentally, there will be Venus and Mars in the frames as well and on Nov. 11-12, a 4th planet will appear (4 TOTAL) when Jupiter appears. This is only the 2nd time that SOHO has seen 4 planets at once. The easiest way to view the LASCO images will is with the Sun-Earth Viewer. - Chuck Beutler's Transit Page - Boring Name, Great Resource
