I'll be (hopefully) watching the transit of Venus tonight at Saginaw Forest. Hopefully:
A) it will be clear enough to see the sun,
B) the viewing glasses will be dark enough not to blind me,
C) there will be enough friends and acquaintances there to share this event that won't happen again until 2117 AD.
If you are not in a place to see the transit (or don't have a means to see it directly), you can watch it live via the NASA site:
If you live in a city that will have a view, head over to your planetarium; they will likely be quite crowded, but you should also be able to avail yourself to their services (and exuberance) there.
And just in case you don't know if your city is in the viewing area, here's the map of where the transit will be visible:
And - because it is a solar event - the starting time will be at the same relative time around the world: roughly 6pm on June 5, 2012 (if you happen to be living in the same timezone as Michigan, that is).
