    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.

    Issued with some hesitance, as I am still suspicious about my timings. If the 
    resids come out bad, try to ad +0.35s and see how it fits then.
    
    The KH was bright during much of it's pass (mag. +1 to +2) and slowly flared to 
    mag. +0.5 at 02:05:45 UTC. It fainted to +4 once in Ursa Major. Points are from 
    two trail images, it was visible in a third too but too faint there to 
    comfortably measure. The first image captures the flare moment (will post image 
    URL later).
    
    I am currently targetting unclassifieds rather than classifieds to get some grip 
    on the timing error variation.
