hello, I've just realised I made a mistake in the date of the unknown bright flasher. It was actually May 8 instead of 9: Location: 51ø 10' N 2ø 57' E Time: May 8th 1999, around 21 h 53 m UT It went from West to East, almost through zenith, through bowl of UMa. Flashing, a secondary maximum, period 4.08 magnitude: about 2 Sorry for this mistake! (probably why I couldn't identify it yesterday) Kurt
