Observed shadow exit for the GPS 2R-2 Delta 2 R/B (24877 97-035B)
that is making very low perigee passes over parts of continental US.

Time of shadow exit: 29 Aug 12:14:53 UTC (5:14:53 am PDT)

Quicksat prediction:
 H  M  S  Tim Al Azi C Dir  Mag Dys F  Hgt Shd  Rng  EW Phs  R A   Dec
 5 15  4   .1 33  63   140  2.5?  2 0  125  11  224 2.6 130  737  39.3
                                       201km    360km

I only saw it for about 15 sec before it disappeared behind a tree.
Mag. was steady and is my estimate.  I don't have an entry for it
in my quicksat.mag file.  It could be much brighter with a better
phase angle.

On the previous orbit it exited shadow right over southern Missouri.
Any observers in that area?
