Double flares from Iridiums (significant dimming between maxima)-- Ir 38 (25043, 97-69E), 27 Feb. 98, predicted 1:57:40 UTC, +3 followed by +2 maybe 15-20 (?) seconds later Ir 44 (25078, 97-77B), 1 March 98, 1:40:15 UTC, +2 followed by predicted +3 at 1:40:50 Might these caused by the satellite reorienting itself during the observation? Unexpected non-Iridium flare-- 1 March 98 UTC; for about 3-4 seconds around 1:56:50, northbound, max. mag. possibly -1.0, below (west of) Cass, at about alt. 25, azi. 325. Upon checking afterward, I got a pretty good candidate: 30.309 97.728 550.

Unexpected paucity of observations on a beautiful night-- Sunday evening (early Monday UTC) in San Antonio, darker than my apt. and work locations in Austin, only managed to see (using one-power) 3 objects (compared with 8 from around my apt. the previous night).... Still uncertain about the ID of the very brightly but irregularly (?) flashing UNID that I and apparently Robert Fenske also saw Friday morning. Ed Cannon ecannon@mail.utexas.edu Austin, Texas, USA
