    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.

    Intermittent clear periods and fields of drifting cumuli. Observed a nice -1 
    flare of Iridium 64. Nice residuals on the image too.
    
    The NOSS 3-4 rocket (07-027B) was observed again, this time between patches of 
    cumuli (hampering photography a bit: the first image is good, the second has it 
    entering clouds hence I dropped the endpoint) and varying between mag +3 and +2. 
    This really is a nice object.
    
    After the 07-027B observation, increasing cloud cover aborted further observations.
