    Our two replies seem to have crossed.
    Mine would imply that ON THE AVERAGE you should look near RA 05:45 RA, 0 
    IF the satellite is geosync, it could be there about 11:50 PM - in graveyard 
    orbit later.
    But it is inclined, probably ascending, and the sun is higher, so if it is 
    rotating near the equatorial plane this would force flashes even further W 
    All in all, it needs a longer observation sequence, or lucky random 
    observations spread over a year to make computations.
    I found two near-geosyncs,
    22205 GALAXY 7             best fit
    20706 DFS 2                    earlier
    and 23132 UFO F3 USA 104 later
    but with only one position given, it could have been a Molniya type orbit ?
