    I took a while getting around to analyzing Greg's other interesting object of last night, which
    turns out to be SBSS 1, observed on 2010 Oct 12, at 17:51 UTC:

    Here are approximate elements:
    
    SBSS 1                                                   629 X 630 km
    1 37168U 10048A   10285.70378281  .00000000  00000-0  00000-0 0    03
    2 37168  97.9733 147.6710 0001000   0.0000   0.1211 14.79000000    08
    Arc 20101012.74-1012.74 WRMS resid 0.026 totl 0.013 xtrk
    
    The arc is 43 s, so the mean motion is uncertain, by perhaps 0.01 rev/d, which results in prediction
    time uncertainty of about 1 min per day since epoch.
    
    SBSS 1 recently completed nine manoeuvres to reach its operational altitude. Spaceflight Now
    published a report with some details of the manoeuvres:
