    Russell Eberst, Greg Roberts and Peter Wakelin, contributed observations
    used to determine one or more of the following element sets:
    
    Russell recovered 84012A on Dec 19 UTC, which he initially reported as an
    unknown, running more than 20 min late relative the epoch Nov 08 elements.
    He made the confirming observations on Dec 21 UTC. He reports that
    coincident with the significantly late arrival, the object no longer is
    steady in brightness, and has a ~1 s period of variation, which indicates
    that it has undergone a small explosive release of some sort. The object is
    the Multiple Satellite Dispenser of the NOSS 1-6 triad, so it has a
    propulsion system, which could have experienced a rupture. Below are
    approximate elements of the new orbit, which has increased about 2 km in
    mean altitude.
