Thanks for the info.

I don't see Cosmos 775 being one of the unknowns at this time. It has angle
path to the geo sat belt, and the unids barely changed with respect to the
geo sat belt over the time I observed them.

Scope I was using.

*Observatory*: iTelescope.Net <http://hosting.itelescope.net/> at Siding
Spring Observatory Australia - MPC Q62

*Telescope*:  0.10-m f/5 Astrograph + CCD

*Timezone*:  UTC +10:00 New South Wales, Australia Daylight
<http://www.timeanddate.com/worldclock/city.html?n=152> savings time is
observed.

Minimum Target Elevation: Approx 20-25° West & South : 35° East : 75° North


*South* 31° 16' 24" *East* 149° 03' 52"

*Elevation*: 1122m   *MPC* Code Q62
