For the next week, the International Space Station (ISS) will be performing a series of bright evening flybys over North America and Europe. The station is very easy to see if you know when to look. Check the Simple Satellite Tracker for local flyby times or you can turn your cell phone into a field-tested ISS-tracker.

On Oct 21st, amateur astronomer Béla Vingler of Győrújfalu, Hungary, caught the space station flying directly in front of the Moon:

The station's winged outline was backlit by the bright debris fields of Crater Tycho as the spacecraft raced across the lunar disk, completing the transit in only a split-second. Because lunar transits happen so fast, careful planning is required to photograph them. The place to start is Calsky.com, which provides precise predictions of ISS transits for locations around the world.
