This morning I observed a brief flare (half second or less) from Tiangong 1. It happened at the highest point of a nearly overhead pass (81 deg) in twilight. I would guess it brightened by about 1 magnitude. This was 49 minutes before sunrise, so the angle between Tiangong 1 and the sun was a bit more than 90 deg. The sky vas very clear. Observation time: 2011 Dec 09, 1408-1413 UTC.
