Short observing session

After many days with heavy rainshowers, it cleared yesterday evening.

I did a short observation run: cut short alas by the return of clouds just before an IGS 1B zenith pass. I did manage to get data on Lacrosse 2 (91-017A),and observed two short bright glints by two Keyholes, USA 186 (05-042A) and USA 129 (96-072A). Lacrosse 2 appearred some 0.1s early.

2005-042A glinted to mag. 0 during less than a second at about 20:01:25 ± 5s UTC. 1996-072A did the same to mag 0 at 20:22:17 ± 3s UTC.

I captured both flares/glints on photograph, but in both cases only the very brief glints show up (almost star-like) and not the fainter rest of the trail, hence no useful positions could be derived from the images and they are not even worth posting here.
