Problems: 

None, everything behaved as it should.

Comments: 

First part of night spent testing the new non-sidereal tracking - observed 3 fast asteroids without problems producing nice, round, star-like images of the asteroids and suitably elongated streaks of stars.  Rolo and Omar deserve applause for developing and integrating a new trajectory engine into the TCS.  It worked flawlessly.

From 01:40am CDT, took Hysteresis Map (not the control map).  Image numbers 487705-487896.  Defocussed 1500microns, AOS off, 4MAP in test mode.  These are good data for investigating axial hysteresis in the M1 radial supports.
