Observations 08 June 2006
----------------------------------------
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.
Used with 75mm focal length f/1.8 lens,integrating for 128 frames
which is equivalent to an exposure of 2.56 seconds per image.
Site 0433 : Longitude 18.51294 deg East, Latitude 33.94058 deg S,

Notes:
-------
(1) #90028 found due to the radio tracking of Ivan Artner and Mike
McCants magic in generating orbital elements.
(2) #90004 positions may have a small spread along track - in the bright
moonlight I could only see the flashes in the integration and not
the start and end of the integration trails. Only the third position
is at the start of a trail. Satellite appears to have a regular flash
period with a smaller flash in between - difficult to determine
period due to integration time used but appears to be around 4
seconds or so.
(3)The 6 inch reflector project is coming along well. Yesterday managed
to get the stepper motors to respond to commands from Mel Bartels
SCOPE program and move the telescope around . CoSaTrak also drives
the stepper motors okay so I now have the option of either tracking
in azimuth/altitude or Right Ascenscion/Declination. Still a few
more trivial things to do before the new scope is fully operational.
Cheers
