Hi all - Had a clear and mild night, a rarity up here at 2728 meters. I observed another pass of Iridium 18, for which the Quicksat prediction is given below: 1998 June 2 TueUT320 1037 H M S Tim Al AziC Dir Mag Dys F Hgt Shd Rng R A Dec Name 5 43 47 .0 52 269C 267 6.6 5 1 481 103 591 1224 29.8 Iridium 18 It gave off a rapid-fire sequence of 9 flashes in about 5 seconds very near the culmination point listed above. The flashes ramped up from magnitude +1 to -1, than back down to +1. The flash sequence may have been cut short by shadow entry. Comparing this observation with another pass of Iridium 18 a couple nights ago, there seems to be a pattern: the flashes occur near culmination, over a period of several seconds. There's a near-zenith pass tonight, so I'll be out looking! Also saw TiPS in the 12-inch: 6 12 25 .1 79 53C 87 6.3 15 4 657 192 667 1643 45.7 TiPS First sighted at culmination with the ends at magnitude 8 and the tether nearly invisible. As TiPS moved to the southeast, the ends faded as the tether brightened, until just the tether was visible just before shadow entry. As twilight increased, I had no problem sighting TRMM at 1x, close to predicted brightness at an observed magnitude +1.6. 10 44 10 .2 30 176C 270 1.7 5 4 219 135 408 2041-20.2 TRMM Also saw the following high-flying objects, with Quicksat predictions: 1998 Jun 2 UT Hr Min Alt Azi Mag Hgt R A Dec Range 23230 ETS 6 94 56A 51 M 5.0 ELDY 7 M2 -1 7 20 27 176 12.9 17716 17 15.4 -23.6 19609 Observed 0720-0750, mag. 12, flsh 9, period 4.5s (40 flashes in 180s). 22694 Galaxy 4 93 39A 127 M 3.5 ELDY 6 M2 0 8 20 41 207 11.6 22431 16 40.4 -6.1 23642 Possible sighting - a magnitude 12 object, not varying much over 10 minutes, 2.2 minutes of RA (about half a degree) east of the predicted position using 6-day old elsets. 21533 Gorizont 23 91 46A 5.0 M 4.5 ELDY 10 M2 -1 9 20 41 186 12.6 22493 18 43.1 -8.7 23664 Observed 0920-0930, mag. 13, flsh 9, period 50s (6 periods in 300s); fainter flashes at quarter period intervals.
