Observations 25 Nov 2003: ------------------------------------ Cosatrak 1 (Computerised satellite Tracking System), 1004x low light level CCD surveillance camera (0.003 lux) with 145mm focal length f/2.5 lens with focal length reducer, field of view 1.89 x 1.43 degrees. Conditions very good - however stopped by cloud Site 0433 : Longitude 18.51294 deg East, Latitude 33.94058 deg S, Elevation 10 metres - situated in Pinelands (Cape Town), South Africa Amendment: ~~~~~~~~~~~ Our ever alert orbit analyst Mike caught an error: The following is INCORRECT: 20344 89 061D 0433 G 20031125181304200 17 15 0222587-550448 39 I+084 05 and should read: 20344 89 061D 0433 G 20031125181304200 17 15 0223229-534947 39 I+084 05 an ENORMOUS difference. At first I could not understand how I could get such a large error in declination then accidentally moved the mouse cursor in GUIDE and the dec jumped from -53d49'47" to -55deg 04'48"-- I have since verified that if the mouse cursor is very close to the border of the field displayed it does this jump so it looks like this could be a minor bug in GUIDE ? The position given by the cursor under this condition is actually the coordinates of the centre of the field of view! Moral of the story ? - dont use the mouse cursor to get positions at the extreme edges of the field. I suspect that I probably bumped the mouse slightly whilst writing down the position ( as I was inside the field of view but very close to the edge ) and it jumped to the wrong co-ordinates. Sorry about that - cant blame the cat!
