The International Space Station & the Space Shuttle Atlantis will be visible tonight in Eugene (& other areas of the west coast.) They will track from the northwest to the southeast above Eugene tonight from 10:35 pm until about 10:42 pm.
Look to the west at about a 30 degree angle from the ground (considering that straight above you is 90 degrees). Although they just separated earlier today, they are still traveling very close to each other and should be visible with the naked eye.
Happy gazing and please leave a comment if you did watch it live.
