I was watching in binoculars as IGS 1B was predicted (using 05100 elset) to pass 2' from Alpha UMa (not on the side of its 6' companion). Instead it passed at least .4 degrees away on the companion's side. 27699 03 009B 5919 G 20050416201623390 17 25 1055326+633737 19 S What these numbers mean: http://www.algonet.se/~b_gimle/IODprograms.htm Later I found that my obs was about 18 s late, and agrees with Russell's : 27699 03 009B 2420 2005041621510050 27 24 0205100+711812 28 S+029 000000 Lower in the North I acquired it in the scope, and got a good (?) obs 1/4 off a vertical 0.1 degree pair at 20:18:02.1, and 1/10 outside an oblique 0.2 degree pair - but cannot locate either of them! I followed it down to 2.7 degree altitude at 20:21:20, but no close star pair on the way down. 24680 96 072A 5919 G 20050416203310010 17 25 0642555+180185 19 S 24680 96 072A 5919 G 20050416203327570 17 25 0614177+221527 19 S 24680 96 072A 5919 G 20050416203358270 17 25 0523202+284217 19 S These are appulses, with no miss distance estimates. 24680 96 072A 5919 G 20050417192202100 17 25 1429304+753559 78 S Found an UNID 1/5 outside a 0.1 degree unknown star pair, rising in the N. 43.1 s later, at 20:37:02.6, it was 1/10 outside another unknown pair near RA 18:00 +43 10544 77 112E 5919 G 20050416232032860 17 25 1415551+195842 18 S 10544 77 112E 5919 G 20050416232049760 17 25 1431944+170523 37 S 10544 77 112E 5919 G 20050416232118520 17 25 1455890+124007 28 S First position well identified, for the others, the tighter star pairs do not quite match my voice comments, and they don't agree. Identified 68040B, observed as UNID 00:50:43.6 and 00:51:01.1. Timing at 20:27:39.9 has no voice recording :-( At 00:00:05.6 UTC I observed the decayer 02037F at RA 21:21:23 dec.+23 31' flashing +7.5 to +9 with about 1 sec period. If it decays on the 29th, its last orbits may be fully sunlit; before its NB leg will be in shadow at mid-northern latitudes, later from N apex down to tropical latitudes. 27475 02 037F 5919 G 20050417000005630 17 25 2122929+232243 28 S+075 05 001000 -- COSPAR 5919, MALMA, 59.2576 N, 18.6172 E, 23 m -- -- COSPAR 5918, HAMMARBY, 59.2985 N, 18.1045 E, 44 m -- ------------------------------------------------------------------------- Subscribe/Unsubscribe info, Frequently Asked Questions, SeeSat-L archive: http://www.satobs.org/seesat/seesatindex.html
