Track Venus as it Moves Across the Sun Tonight

Track Venus as it moves across the sun June 5 and 6, 2012. And guess what? There's an app for that! It's called VenusTransit and it's free. You can find out which part of the transit will be visible from wherever you are and at what time you should be looking up! Then you can participate in a worldwide tracking experiment by documenting the exact moment Venus appears within the sun. The app then records the exact GPS location and time. If you don't get to watch in person, you can see it and learn more about it on NASA's website.
