The newly unclassified object, 10994, matches Ed's observation
very well.  We were able to see it about 40 degrees up in the
west last night.  It reached magnitude 2 at maximum even though
the phase angle was rather unfavorable.  I estimated that the period
was about 60 seconds, but I did see some secondary maxima.

Object 23093, Cosmos 2279 Rk, was timed with a period of 9.2 seconds.

Object 90012, MDS Fairing 2, seemed to be about 1 minute late at
20000 miles, flashing to magnitude 7 or 8 or 9 about every 8.03 seconds.
(Ed's timing)

Object 27435, Ofeg 5 Rk, was timed at very nearly 1.0 second.

Object 00011, Vanguard 2, was seen varying from magnitude 9 to 10
at a range of about 700 miles.

Debris object 12171 was seen to be varying from about magnitude 6.5
to 8.0 with a period of about 5 seconds.
