    For those SeeSaters in the northern hemisphere (but not too far north),
    satellite 26692 = 01-004C = "GPS 2R-7 PAM-D r" offers a chance to see
    a REALLY FAST moving not-about-to-decay object. It is in an eccentric
    orbit currently about 160 km x 16400 km (at launch, its orbit was
    approximately 180 km x 20400 km) and its argument of the perigee
    will reach 90 degrees next week.  As its inclination is approximately
    38.8 degrees, observers near that northern latitude have a chance to
    see it in the evening at or near its perigee when it is moving at some
    35060 km/hour or 9.74 km/sec.
    At 23:28.8 UTC 2001 Oct 08, we saw it at apparent magnitude 4-1/2 or 5
    (very hard to judge due to its speed), corresponding to an "intrinsic"
    magnitude (full phase, 1000 km range, cosine phase law) of +7, or a
    "standard" magnitude (90deg phase, 1000 km range, Lambert phase law) of +8.
    Clear and dark skies!
