(1) Quite a good night except for a light breeze which occassionally messed up images (2) As usual majority of measuring done with APEX ( have number 16 in report above). Satellites done manually have number 56 in report) . (3) 90084 tried but at extreme range ( 120000 kms),and low elevation in east with bright city lights prevented exposures longer than 15 seconds so was only able to get down to mag +15 so either the satellite is fainter than 15th magnitude or it aint where the prediction said it should be. (4) Following satellites are now lost: ( have obviously done an orbit change: UFO-F04 FLEETSATCOM 8 DSP-F22 (5) Ekran 5 ( 96098 ) is also lost. (6) For Derek -- APEX took 55 minutes to process 177 images during which time I did all the manual images on another pc :-)). I wasted a further hour in checking that APEX had correctly identified all the strays and another half hour or so in sorting this report out - eg removing surplus observations- eg DSP-F19 99017A had 24 positions whilst 90040 had 11 positions originally. (7) Seeing 15 arc seconds Cheers Greg ------------------------------------------------------------------------- Subscribe/Unsubscribe info, Frequently Asked Questions, SeeSat-L archive: http://www.satobs.org/seesat/seesatindex.html
