Sunday evening (15 June UTC) from outside my apartment (poor
location -- lots of nearby bright lights!), about 30.3086N, 
97.7279W, 150m.

Iridium 20 (24871, a.k.a. 18) -- two episodes of consecutive 
one-power flashes -- nine flashes that ended at about 3:28:31 
(plus/minus 5 seconds [The next episode caused me to forget if 
the end of the first episode was 28:26 or 28:36!] and 13 of 15 
flashes (that is, two weren't seen) that ended about 3:30:05.

Iridiums 39 and 42, flares as predicted by Iridflar.

USA 81 (21949, 92-23A), sparkled to about +2 near culmination
(alt. 80, azi. 276).  I think it was late, but I was showing it 
to a neighbor and didn't get any sort of timing.  (Having seen 
it before in Mike McCants' telescope, I strongly recommend this 
one; it's really, really neat when the sparkles are seen with 
magnification!)

Mir VDU (25294, 86-17MQ), possibly as bright as +3.  (Seen at
least once before at one-power.)

Nice Mir pass into shadow, showed it also to a neighbor.
