    Scott Campbell, Mike McCants, Greg Roberts and Peter Wakelin, contributed
    observations used to determine one or more of the following element sets.

    Peter recovered 98005A, four months after it was last observed. The above
    elements are approximate; especially the mean motion.

    PAN recently relocated from 34.5 E to 32.8 E.

    The STSS Demo satellites continue to separate, and their separation is now
    well beyond the expected 35 deg of central angle. I doubt there is a problem
    with either spacecraft; more likely, the 35 deg value is based on out-dated,
    garbled or misunderstood information; or the limits of communications
    cross-links are being tested.
    
    09790A                                                 215 X 30211 km

    I had hoped to get in a few more; especially some of the LEO objects, but I
    have run out of time this morning.
