Tonight I observed from site 5918 a nice flash series from Ir 44 (tum), completely at 1-power. I first saw it (because of clouds?) below the handle of Big Dipper, the second (first one timed at 18:55:33.4 UTC 2001-09-09) below epsilon UMa, both were -3 or -2. There was a phase shift after the second timed flash, next flash (mag +2) only eight seconds after, followed by eleven flashes at 23 seconds interval - all except the last one, at 8 deg. alt. (still at 1x), had -tive magnitudes. Analysis with SYNODIC.EXE shows a clear synodic (!) effect - period around culmination is about 23.00 s or larger, about 22.80 s low in the N. Best fit average is 22.87 seconds period. Lap times: 23.23 8.68 22.98 23.04 22.96 22.98 22.83 22.83 22.85 22.75 22.71 22.86 I also observed what seems to have been the new Centaur and two payloads. Some 75% cloud cover, illuminated by Moon and city lights, and no tape recorder at hand, made stellar identification uncertain. Magnitud about +3 steady, payloads +5 steady and separated by about 2.5 degrees (6.3 seconds) At 21:24:26.7 UTC RA 01:13:36 Dec.+28 39' 21:24:49.1 7 degrees left, in Dir=260 deg. 21:25:38.5 RA 02:27:18 +32 00' 21:26:47.2 First payload near 01:20 +30 21:26:53.5 Second payload at same place -- bjorn.gimle@tietotech.se (office) -- -- b_gimle@algonet.se (home) http://www.algonet.se/~b_gimle -- -- COSPAR 5919, MALMA, 59.2576 N, 18.6172 E, 23 m -- -- COSPAR 5918, HAMMARBY, 59.2985 N, 18.1045 E, 44 m -- ----------------------------------------------------------------- Unsubscribe from SeeSat-L by sending a message with 'unsubscribe' in the SUBJECT to SeeSat-L-request@lists.satellite.eu.org http://www2.satellite.eu.org/sat/seesat/seesatindex.html
