Element sets show a very large variation in mean motion and eccentricity over a time span of one week according to Mike.The 90-102E and F objects were "aux motors" which decayed in 1998 and 1991 and 90-102G was only catalogued in June 2001. Mike suggests that it is a piece of mylar and the optical characteristics and high drag support this. Thanks also to Scott Campbell for his input. This object is in a 159.87 minute orbit inclined at 45.92 degrees and ranging from 1598 out to 5163 kilometres.The latest element set for this object verifies that Mike's "guess" is correct. Well done Mike! I will attempt to observe this object again just for the satisfaction of knowing what I am looking at. (2) The unknown #91063 reported today may not be an unknown and I would be perfectly happy to accept that it was a bird . It was very faint and I was not really able to detect any flapping motion. Night birds usually fly over in groups so this may be an ostracised bird. (3) Satellites #13172,#14728 and #26906 tracked in very bright twilight so reference stars rather few and faint. (4) Geostationary #90002 may be questionable. I did a long exposure of the predicted area and found a short trail that may or may not be a satellite - Ill have to wait for darker skies to be more certain. (5) Final Ivan Artner reports that #90027 is running late by at least 13 minutes which indicates that an orbit change has been made. Ivan monitors the satellites radio transmission and is a good example of how the radio and visual tracker can work together. Now that I know roughly how late the satellite is running I should be able to re-locate it and track it until it is moved yet again. Wonder if it is a Trumpet satellite? (6) My apologies for the mail problem I am currently having. My reports reach SeeSat intact but in being converted to the digest form most of the contents are lost so all I get in my digest is the heading. Are other receipients having the same problem? I havent changed anything this side that I know of that should cause this problem. My server is currently having problems so it looks like there are quite a few hours delay before this actually reaches SeeSat. I wonder if its because the local government has just passed a bill in parliament allowing telephone tapping and interception of e-mail to be legal.
