    Scott Campbell, Russell Eberst, Kevin Fetter, Tim Luton, Pierre Neirinck, Alberto Rango, Greg
    Roberts, Peter Wakelin, Brad Young, and I, contributed observations used to determine one or more of
    the following element sets.
    
    DSP F7 r2                                            35733 X 35834 km

    Alberto reported the position of an object that appears to correlate with Kevin's UNID of Sep 20,
    which I suspect to be XSS-11 (05011A / 28636):

    Technical problems caused the time of the observation to be lost; however, I was able to estimate a
    time that yielded a reasonable solution with good residuals:
    
    XSS-11 suspect                                           375 X 698 km

    I am still using the 70000 ID, because I believe it would be prudent to have a confirming
    observation before declaring that 05011A is found.

    Scott could not find AEHF 1 (10039A / 36868) in difficult conditions; however, Mike McCants believes
    that he observed it in the last known orbit, on Sep 29 at 2:35 UTC. Later, he could not see it.
    Moonlight was a likely factor.
