    Russell Eberst, Steve Newcomb, Alberto Rango, Greg Roberts, Ian Roberts, Peter Wakelin, Brad Young,
    and I, contributed observations used to determine one or more of the following element sets.

    OTV 1-1's orbit maintenance manoeuvres make it difficult to determine mean motion and rate of decay
    with precision.

    AEHF 1 continues its HCT (Hall Current Thruster) burns, which have raised its perigee ~1600 km, and
    decreased its inclination ~1.3 deg, since they began, three weeks ago. Mike McCants has greatly
    facilitated observations, by providing fairly accurate predictions of the elements, based on the
    expected effects of the manoeuvres. Here is Mike's latest update of the actual orbit, based on Kevin
    Fetter's observations last night:
