Transit of Venus resources

February 17, 2012

I mentioned a couple of posts ago that there will be a transit of Venus across the face of the sun on June 5/6, an event that comes along only twice per century. The last one was in 2004, and the next one will be in 2117. I’m starting to collect online resources that have to do with the transit, and I’ll probably set up a separate page on the sidebar to make them easier to find (hey, look, I did!).

Transit of Venus .org is probably the most comprehensive online resource for the upcoming transit, with links to tons of other transit sites and resources.

Astronomers Without Borders have an excellent transit page and blog going here. Particularly useful is their Local transit times page, which will show you the timing and path of Venus in front of the sun depending on your location. Here’s a screenshot of the map I generated for Claremont, California:

Note that the transit will still be in progress when the sun sets at 8:00 PM, so I’ll see about 80% of the transit (assuming no clouds!) but not the whole thing. I’ll take what I can get!

Also at that site is a sweet set of instructions on how to build a “sun funnel” projection screen to show lots of people the sun at once with a single telescope. Here’s a pic borrowed from the site of the sun funnel in action:

I am SO building one of those!
