    Derek Breit, Scott Campbell, Kevin Fetter, Alberto Rango, Greg Roberts, Peter Wakelin, Brad Young,
    and I, contributed observations used to determine one or more of the following element sets.
    
    The analytical and observational efforts of several of us to find the AEHF 1 objects have come to
    fruition, and Scott Campbell and Peter Wakelin have reported observations. I believe the following
    to be fairly accurate, but the arc is short, and the rate of decay of the Centaur is somewhat
    uncertain.
    
    AEHF 1                                                 285 X 49983 km

    Standard visual magnitude of both objects is approximately 4 (1000 km, 90 deg phase angle).
    
    Kevin made another video of OTV-1 this morning, from which I extracted the following:

    I have run out of time this morning, but plan to analyze Peter's other observations later.
