I did a photographic search this evening (1 April), doing a continuous shoot between 19:44:00 and 19:53:00 UTC of an 18 x 24 degree area centered on the nominal position for 19:47:30 UTC. The pattern was: 10 seconds exposure, 10 seconds pause, and next 10 seconds exposure, etc... No sign of Lacrosse 2. Lacrosse 4 on the other hand, passing through the same area around 19:46 UTC, was captured on several images. So Lacrosse 2 indeed is gone, unless it passed before 19:44 UTC. - Marco Op 1-4-2011 20:32, Ted Molczan schreef: > I now believe that Lacrosse 2 (91017A / 21147) made at a major orbit manoeuvre, probably to de-orbit, in the early hours > of 2011 March 26 UTC. > > Pierre Neirinck reports that he observed Lacrosse 2 on Mar 25 at 20:19 UTC.
