Observations 09 JUNE 2010
----------------------------
Cosatrak 1 (Computerised satellite Tracking System).
Camera mount now carries two systems that can be operated
together as two totally different sytems and computers used.
Meade DSI Pro II Monochrome CCD camera without filters.
using integration times of 5 sec min to 25 seconds maximum
depending on brightness of sky in particular area.No image
processing done, but some done automatically in the auto reduction
software.
Used with 80MM focal length f/2.8 Nikkon telephoto lens.
Image scale is 20.393 arc sec/pixel and field of view 264 x 192
arc minutes.( 4.39 x 3.21 degrees). Shows 13th magnitude stars
with about 5-7 second exposure. Maximum exposure is ~35 sec because
of city lit sky, decreasing to 15 seconds at elevations of 20
degrees or less.
Exposure time is recorded in the FITS header and is derived from
the PC clock which is accurate to within about 1 second.
Site 0433 : Longitude 18.51294 deg East, Latitude -33.94058 deg,
Elevation 10 metres-situated in Pinelands (Cape Town),South Africa

NOTES:
=======
(1) Main purpose was to find VORTEX 6 which has been lost for several
weeks as a result of an orbit re-boost. Whenever the mean motion
becomes greater than about 1.0031 - 1.0032 revs/day the old 1989
satellite does a burn to change the mean motion to about 1.0022
revs/day - this seems to occur roughly every 200 days.
(2) Still a LOT to measure as I took over 80 images along the eastern
half of the Clarke belt ( dec about +5.3 degrees for me) to an
approximate declination of zero degrees. LOTS of satellites seen ..
Cheers
Greg
