A Lacrosse 4 flare, and a Lacrosse 5 "disappearance trick"
Highlight of the evening was a fine short and bright magnitude +0.5 flare by Lacrosse 4 (00-047A, # 26473) at 18:53:00 +/- 1s UTC, just before it entered into eclipse in Taurus.
Earlier that evening, Lacrosse 5 (05-016A, #28646) did the opposite: it did its "disappearance trick" again at 18:31:27 +/- 2 s UTC, some 1.5 minutes before eclipse entry. The camera was open while it happened: the first of below two pictures, where it is already much fainter than before and disappears. The second picture below was taken a minute before the first, and shows just how bright Lacrosse 5 was at that time (about mag. +1.5).
After it disappeared, it did not re-appear visually (naked eye) or photographically.
Update: Lacrosse 4 (00-047A) was about 0.8s late relative to a two week old elset. Lacrosse 5 was on-time.
After image enhancement in Photoshop, the third image does show Lacrosse 5 as well, but barely. It must have been mag. +4 or fainter.
Bruce MacDonald from the UK reports he observed Lacrosse 5 "disappearing"as well on seesat.
