    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.

    Another nice and clear night, after rainshowers earlier in the day.
    
    06-057A (USA 193) became quite bright (+0.5) during it's northwest pass. It was 
    2.5s late relative to Ted's elset 07202.04020244.
    
    Two images on two separate passes for 00-047A (Lacrosse 4) yield two different 
    sets of delta T's, so obviously one image (& pair of positions) has a timing 
    error in it. I leave it to the analysts to decide which one.
