XSS-11's rocket body (05011B / 28637) failed to appear on a difficult morning twilight pass on 2005 Sep 06, near 09:57 UTC. This was about 21 minutes before the start of civil twilight (sun was 9.5 deg below the horizon); phase angle was poor. Predicted magnitude was 8.6, and I could barely see stars that faint with my 11x80 binoculars. Position was 30 deg above the eastern horizon, in a clear sky. The illumination of the orbit at my latitude will improve considerably in a few weeks. 05683A was 20.4 s early, relative 10 day-old elements. 24680 96 072A 2701 G 20050906014649450 17 25 2335425+310965 37 S 24680 96 072A 2701 G 20050906014752150 17 25 0020086+485193 37 S 24680 96 072A 2701 G 20050906014822650 17 25 0054334+562103 18 S 24680 96 072A 2701 G 20050906014905800 17 25 0203249+642066 57 S 24680 96 072A 2701 G 20050906015035780 17 25 0510058+681593 37 S 24680 96 072A 2701 G 20050906015118780 17 25 0613941+655345 28 S 90040 05 683A 2701 G 20050906025354340 17 25 1758627-165288 37 90040 05 683A 2701 G 20050906025421220 17 25 1809556-185225 87 24680 96 072A 2701 G 20050906032549470 17 25 1530178+402412 27 S 24680 96 072A 2701 G 20050906032735970 17 25 1348638+482316 37 S IOD format: http://www.satobs.org/position/IODformat.html Site 2701: 43.68764 N, 79.39243 W, 230 m Ted Molczan ------------------------------------------------------------------------- Subscribe/Unsubscribe info, Frequently Asked Questions, SeeSat-L archive: http://www.satobs.org/seesat/seesatindex.html
