Observations 01 March 2005 Part 1 --------------------------------------------- Cosatrak 1 (Computerised satellite Tracking System). MINTRON low light level CCD surveillance camera (0.005 lux typical in non integration mode) and 0.00005 lux in STARLIGHT mode with 128 frame integration. Due to bright sky it is not worthwhile integrating more than 48 frames which is equivalent to an exposure of 0.96 seconds. Used with 145mm focal length f/2.5 lens giving a field of view of about 2.55 x 1.86 degrees and easily showing 12th magnitude stars. Not the best lens optically but the most useful in terms of field of view and magnitude penetration. Data recorded on DVD R/W disks - will be kept for 1 month and then re-used - just in case any queries as Im always making mistakes!

(2) #28538 Noss 3-3r observed in very bright twilight conditions. Sorry Ted, the other NOSS 3-3 objects did not make observable passes. (3) I think I have "recovered" #23712 MILSTAR DFS2 which hasnt been observed for a while. I did a "box" search around the predicted location and found it about 48 arc minutes "off predicted position". (4) #90020 really an impressive flasher, flashing for most of the 5 minutes I tracked it with a good percentage of the flashes being naked eye. (5) Strays observed by accident : #19649 Cosmos 1980 #25872 Globalstar MO48 #01001 Titan 3A (Truss) - nice and variable #26476 Delta 3 R/B at 13307 kms, orbit 190 x 19936 kms, i = 27.39, P = 349.6 mins. probably more to come as Im only halfway through the DVD recordings. (6) Unknowns called 99999 and 99998 - these are high altitude - I suspect at around 37000 kms and in the short period tracked appeared to be related - both travelling the same direction and speed and close together. The first object appeared to have irregular flashing - the positions are when it flashed, whilst the second one flashed approx every 75 seconds or so. The second one was brighter, flashing to about mag 10 whilst the other one was about magnitude +10.5 - both invisible when not flashing. I dont find a match for these objects in my elements data.
