    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.

    Bad luck this evening, which was cut short by incoming clouds. 1991-017A might 
    have been 0.1 s early.
    
    Observed two KH's flaring, USA 186 (2005-042A) and USA 129 (1996-072A).  Even 
    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.
    
    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.
