    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.

    Lacrosse 5 was very faint during 1st pass (17:07 UTC, late twilight), a zenith 
    pass where it should have been bright. Flare predicted for 17:06:59 UTC was not 
    observed. Trail very marginal on image, dropped 1st point.
    
    Lacrosse 2 also in image but trail too marginal because it was in local cirrus 
    patch. Observed at mag. +2 in zenith.
    
    Lacrosse 5 was much brighter during the 2nd pass (18:50 UTC), lower in the sky. 
    Good bright crisp trail on image.
    
    My results suggest it was 0.2s late and on-track.
