    Method: Canon Digital Ixus 400 + ASTRORECORD astrometric software.
    Camera at manual mode, "10 second" (= 10.7 second) exposure, wide field
    f2.8/7.41 mm.

    Nice batch (to make up for yesterday?), including one morning observation 
    (05-016B). Two KH flares as well: 05-042A flared to -1 at 20:07:40 UTC, and 
    96-072A flared to -1.5 at 20:21:05 UTC. Three good trail images on 96-072A. I 
    measured the start of the trail of 05-042A only as it was fading after the flare.
    
    96-072A: 1.0s early and 0.05 off cross-track relative to 07099.85651120.
    05-042A: 1.0s early, on-track relative to 07100.80397369.
    91-017A: 0.25s early relative to 07094.94374035.
    05-016B: 2.1s early relative to 07095.10725200
    
    I had the impression that 91-017A was somewhat irregular in brightness.
    
    ISS was nice and bright, sailing below Leo.
