Have you heard of iridium flares? There are 66 satellites in orbit, owned by Iridium Communications, used for satellite phone communication. These satellites have three door-sized antennas that occasionally reflect the sun's light, which is seen as a flare from earth.
There are a few good chances during the next couple of days to witness one of these satellite flares: Sunday night around 8:42pm will be the first opportunity. Monday night brings two more chances - at 8:36pm and again at 8:37pm. Check the site below for details. Happy satellite hunting!
