Nice bright sat (Lacrosse 2)

Yesterday evening was clear (it is clouded again now),
and I catched Lacrosse 2 (#21147, 91-017A) making a very
nice pass over the rising Pegasus square at a steady
mag +2. The sat was seen visually, and the trail shows
up well on the image too. The startpoint measured was
very close to the last TLE for 21147, 05232.87066994,
the endpoint is off by some 0.15 seconds. The fit is
as follows (using Scott Campbell's SatFit):

AZ EL ASP XTRK deltaT Perr
( 1) 91.14 49.19 114.34 0.01 0.03 0.016
( 2) 96.63 46.27 118.46 0.01 0.18 0.082

Maybe this indicates there stil is some slight calibration
problem with regard to the exposure duration of the camera.
