One-power observations Tuesday evening (early 16 June UTC), from the Univ. of Texas at Austin campus, 30.286N, 97.739W, 152m (poor location). (And I stranded myself without a digital timepiece, so the times are rough, to say the least.) Iridium 11 -- one very bright flash a bit after culmination at about 2:23:40 (?). (There may have been more to see, but while I was trying to watch it, a couple of people asked me what I was looking at....) Iridium 21 -- visible for quite a while beginning after its 2:40:44 culmination; reached at least zero magnitude with a sort of double-max flare-like appearance pretty close to 2:42:00. It began to dim, so I wrote down the time. Then when I looked up again after 3-4 seconds, it was bright again. Then it remained visible for quite a few more seconds. This seemed more like a flare than a tumble. To the best of my recollection, this was the first time that I've seen Iridium 21 at one-power. Iridium 20 (24871, a.k.a. Ir 18) -- eight bright one-per-second flashes that ended about 2:54:45 (very near its culmination). Iridium 15 -- flared as predicted by Iridflar (+1). Other fun things: Meteor 1-4 Rk (04394, 70-37B) chased down Cosmos 2297 Rk (23405, 94-77B); their closest approach was about 4 or 5 degrees separation at 2:39:49. USA 81 (21949, 97-30G) -- again visible sparkling at one-power. Cosmos 673 Rk (07418, 74-66B) -- bright, maybe at least +1.5. Nice pass of Mir in twilight (solar elev. -6 deg.). 18 objects seen at one-power -- really nice night! Ed Cannon -- ecannon@mail.utexas.edu -- Austin, Texas, USA
