    I tried your elset and selected at random a place
    (Burntwood, England) and time (2005-10-17 18:30),
    when your object was predicted by SkyMap at
    RA 21:16 dec.+47.0, range 31127 km.
    
    Using Mike's classfd.tle and all Space-Track within
    26000-34000 km range and a 4.6*6 degree field over
    30 minutes I found no other object.
    
    Even in a much larger field, I found only one satellite
    on a parallell track, but too early and too low ?
