We had trouble with the Agile rotator tonight.  It checked out fine in the afternoon, but during observing the trouble occured between +115 and +155 while tracking in the positive direction.  We got a motion error that cleared easily approximately every 10 degrees.  After 155 (which was a motor output disabled error) we decided to unwrap the rotator.  I verified by eye that it was not lost, and that the weights (which are now bolted) were still in place.
Next, we had trouble with Don's TUI crashing.  I sent an email to Russell.
Seeing was good in the evenening, then got a but variable during second half.  It was excellent at the end of the night, just in time for the humidity to  start rising.
