Notes:
-------
(1) Prime purpose was to locate objects that appear in the current ESA
Catalog #10. Stopped by cloud after about 90 minutes observing.
The suspected DSP objects observed showed characteristic DSP optical
behaviour.
(2) Unknown object - first seen very briefly at magnitude 8 and faded to about
mag +13 for rest of track across field of view. No attempt was made to
follow it so the observed arc will give a meaningless orbit but this is the
orbit derived:
epoch 2008060.8035532 inclination 20.3 degrees RA node 137.77 deg
eccentricty 0.758 arg perigee 202.36 deg mean anomaly 82.136 deg
revs/day 7.41828.
Looks like debri from an Ariane launch.
Cheers
Greg
