    I attempted to observe MAST on 2007 Apr 25, at 02:48:00 UTC, -20 s / +60 S, but
    did not see any satellite on the predicted track.
    I used the epoch 07114.69437349 TLE of object 31126 / 07012K.
    I observed from Site 2701: 43.68764 N, 79.39243 W, 230 m
    I was aimed at RA 15:57, Dec +54:46, 2000.0
    Elevation was 48.2 deg; range 997 km.
    Observing conditions were good. There was no wind, and the sky was clear.
    Despite the first quarter moon, I could see to about mag 9.5, using 25x100
    binoculars. The limiting magnitude for a rapidly moving satellite would not have
    been as faint. Angular velocity was 0.42 deg/s, so it would have crossed the
    undistorted portion of my FOV in about 4 s.
    I intend to search again as weather permits.
