(2) The first three positions for 25991 are accurate as satellite steady so ends of satellite trails clearly defined. By the time of the 4th position the satellite was flashing every 1.98 seconds and satellite trail ends not well defined. (3) #23533 difficult as trail faint so ends of satellite trail not well defined. (4) The unknown ? may have been a meteor and I caught it in the middle of two exposures so duration not really 2 seconds. First exposure was quite bright, second exposure much fainter and faded out. Nothing seen before or after these exposures. Not the first meteor recorded tonight. ERRATA: -------------- Report for 24 August 2009 #2 : The SL-12 R/B(2) in "Strays seen" was given the wrong identification (#27691). It should be 08033D #33111 Report for 23 August 2009: Mike queried one of the three positions of 90077. APEX remeasured the four images obtained and here are the results - essentially the same as before. 90077 07 757A 0433 G 20090823185120000 16 15 1619093-262400 28 +126 01 90077 07 757A 0433 G 20090823185352000 16 15 1620375-262011 19 +119 03 90077 07 757A 0433 G 20090823185511000 16 15 1621233-261806 98 +124 03 90077 07 757A 0433 G 20090823185633000 16 15 1622289-261717 49 +121 08 Cheers Greg ------------------------------------------------------------------------- Subscribe/Unsubscribe info, Frequently Asked Questions, SeeSat-L archive: http://www.satobs.org/seesat/seesatindex.html
