Hi, all! A 9 Apr 1998 I waited the predicted flares of Iridium28 and Iridium29 (18:16UT and 18:25UT). The sky was not dark (full moon). The limiting magnitude of dimmest stars was about 4...5 mag. Approximately at 18:13UT I have seen a flash of a unknown satellite in several arcminutes from Mizar (Zeta UMa). The brightness of a flash was about 2 mag, duration of the 5...6 seconds. The satellite moved on north-east. Today I have tried to find this satellite on new elset (molczan.tle, 14 Apr 1998), but this satellite has not found out. As gives molczan.tle, at 18:08 in 5 deg from Mizar has passed Cosmos 407 r. However, it has only 5 mag! Somebody observed flashes of this satellite? Or there is some more idea?
