I definitely agree with Bev and Kevin about the additional track. Using ObsReduce and Express 3A elsets for 08066, I find that the start of exposure appears to be 21:09:42 UTC +- 2s, and the coordinates of the start of the faint track 07:42:01 -03:35:27 (2000.0) +/- 0.005 deg (ref.star sep.=10') Including ESA and classfd TLE I find one object remarkably close in declination, reaching this position 879 s later: Unknown 051201 #90043 05835A But I'm puzzled by ObsReduce's time error - from my SkyMap predictions I'd say the object is 18.5m early! 90043 05 835A 9937 G 20080305210942000 28 25 0742010-033546 37 S (as always, IOD format: http://www.satobs.org/position/IODformat.html) 9937= 8.600 W, 37.190 N This elset works best with SkyMap SGP4 UNID 2008-03-05 1 98565U 08565A 08043.73941061 0.00000000 00000-0 00000-0 0 06 2 98565 2.0677 38.3472 0008523 188.8780 175.2400 1.00270000 09 whereas this works best in ObsReduce (SGP4?)

The faint track is up and to the left of the bright track in the first frame only. It is more or less the same length as the bright one. Using allsats from SpaceTrack there is nothing in that area at the time when Express 3A matches the position of the bright streak. ------------------------------------------------------------------------- Subscribe/Unsubscribe info, Frequently Asked Questions, SeeSat-L archive: http://www.satobs.org/seesat/seesatindex.html
