John (and others):

It would be helpful in the future if you included the date of the
observation.
"This morning" or "last night" can lead to a +/- one day ambiguity,
especially
considering the international coverage of this list and the variable posting
delay times.  For example, Microsoft Outlook says your message was
sent on 12/20 at 3:56 am, but it doesn't say if that's UT, your local time
(EST, UTC-5) or my local time (PST, UTC-8).  I'm assuming my local
time, in which case the date was 12/20.

I found your satellite:  UHF F6 R/B (#23697).  This Centaur rocket body
is in a fairly elliptical orbit (ecc = .66), but it was approaching perigee
during your pass.  Here is a not-too-recent element set:

UHF F6 Rk
1 23697U 95057B   98344.60237900 +.00007004 +00000-0 +17917-2 0 07994
2 23697 026.8586 071.4872 6616404 113.3326 326.4220 03.15139672035115
