BS/Yuri 3A's half-period was about 95.5 >seconds; its first two and last flashes were very bright, Ed and I observed Yuri 3A last night from BCRC. (Designation corrected above to 90-077A.) I observed two "double flashes" at an interval of 6:22.6. This is 4 times 95.7 seconds. The double flash was magnitude 8 and 5, but some other later flashes were apparently about magnitude 3. Other faint flashes and tumbles were observed at intervals of 48 and 24 seconds relative to the 95.6 second period. Observed from before 3:56UT until about 4:15UT. Ed noticed a naked-eye Telstar 401 flash about 2:48UT. I timed 5 cycles to obtain a period of 134.0 seconds. It faded after that about 3:01UT. Superbird A was seen in the 8 inch from about 3:11UT until about 3:15UT. This series of flashes was only about 8th magnitude. Then the normal series of alternating flashes was seen from about 3:23UT until about 3:31UT. I estimated that "phase shift" occurred about 3:26:30UT, but it seemed to me that the two phases were not separated in time by as much as they were a couple of years ago. Also timed: 24285 FAST period 2.5 seconds, 25789 Quikscat period 3.6 seconds, 27494 Cosmos 2392 Deb 02 37H period 5.0 seconds, 08398 Delta Deb period about 10 seconds, 09864 Palapa 2 PKM period about 40 seconds. What? PPAS entries? I don't believe it. :-) Desig Date Time Ob Time Unc Cyc Per Comments 90- 77 A 02-11-24 04:09 MM 765.2 0.5 8 95.7 fl to 3 or 5 93- 77 A 02-11-24 04:01 MM 670.0 0.5 5 134.0 fl to 1, 5, 9 89- 41 A 02-11-24 03:27 MM 180.8 0.2 8 22.60 fl to 3 96- 46 A 02-11-24 01:56 MM 25.1 0.3 10 2.5 tumb to 9 99- 34 A 02-11-24 01:05 MM 64.2 0.3 21 3.6 mag 6-7.5 02- 37 H 02-11-24 01:17 MM 55.1 0.3 11 5.0 mag 6.5-8 74- 89CA 02-11-24 01:13 MM mag 8-9, per~10 77- 18 B 02-11-24 00:40 MM mag 10-inv, per~40 Mike McCants Austin, TX (30.3N, 97.8W) ----------------------------------------------------------------- Unsubscribe from SeeSat-L by sending a message with 'unsubscribe' in the SUBJECT to SeeSat-L-request@lists.satellite.eu.org http://www.satellite.eu.org/seesat/seesatindex.html
