(2) #99906 - interesting flashes.For most of the pass observed it showed minor variations in magnitude but for about two minutes, when the phase angle was 11-12 degrees, it flashed quite brightly about 2-3 magnitudes brighter. I tried to determine a period and the following are times of all flashes seen: 16:58:01.3, 16:58:15.0, 16:58:33.4, 16:58:40.6, 16:58:41.0 16:58:47.4, 16:58:54.8, 16:58:55.3, 16:58:56.1, 16:59:02.8 16:59:03.3, 16:59:09.2, 16:59:09.7, 16:59:17.6, 16:59:34.6 16:59:35.0, 16:59:35.5, 16:59:49.0, 16:59:49.4, 16:59:50.0 generally there would be a gap of quite a few seconds then two or three bright flashes in succession spaced approximately 0.4 to 0.5 seconds. Not all flashes were of equal brightness.
