I've taken a look at Rainer Kracht's observations of Superbird A (Norad #20040, 1989-041A) and have computed a solar-panel normal vector at the time of his first flash, as well as at the time midway between his first and last flash: (All times UTC) 2/1/97 17:28:30.00 16h 20m 54s -7d 02' 50" 2/1/97 17:39:01.02 16h 26m 28s -6d 49' 31" (Note that since Rainer's last flash was flash #54, 17:39:01.02 corresponds to a time halfway between flash #27 and #28. The actual solar-panel normal should be close to the 2nd line above, since this should theoretically be the time when the sweep of the specular reflection centroid was closest to alignment with Rainer's location.) When compared with previous values (from Sept/Oct '96), it appears that the satellite rotation axis has changed. Further observations are needed to pin down the current rotation axis. --Rob
