    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.

    In a sky with a touch of haze I catched Lacrosse 2 (91-017A) while flaring to 
    mag -1.5 at 21:54:48 UTC. Very well defined trail on the image.
    
    Cross-track error is 0.05-0.06 deg., which is a true deviation imho as it is too 
    large to be a measurement inaccuracy, especially given the fine trail image and 
    other fit results. Reference star position consistency 22", delta T is 0.02 
    resp. -0.01 sec relative to elset 06159.92449946, overall positional error 
    relative to this elset 0.050 resp 0.057 deg, cross-track in this case.
    
    Observations were done with a pleasant outside temperature of +24.5 C.
    
    - Marco  :-)
