    Observations with a time span of over 3 hours by Greg Roberts
    have determined that the object is very nearly stationary in
    longitude with a non-zero eccentricity:
    Unknown 030305
    1 90013U 03564A   03068.43047270 0.00000000  00000-0  00000-0 0    08
    2 90013   6.9789   5.1374 0035383 193.9488 166.3891  1.00270500    07
    It seems possible that this object has been here for a long time
    and that it is now anomalously bright due to specular reflection
    as the sun goes near the equator.  If so, it may fade over the next
    few weeks.
    One PanAmSat (the westernmost of the three) was observed by Ed with his
    unaided eyes (mag 4) on Saturday evening some 20 minutes before shadow
    entry.  As we watched through the telescope, that one faded rather quickly
    and the other two brightened until the original object was the faintest
    (about magnitude 8) and the set of three matched what we observed Friday
    evening just before shadow entry.
    But 90013 was bright for over three hours, not just 20 minutes.  Some
    of the other objects (Galaxy 11, XM-1) seem to be bright (mag 8 - 9)
    for many hours during flaring geosync season.  Solar panels with
    "concentrators" to give this effect with two or more reflections?
