                ------------- ACTIVITY LOG --------------
 Observing Specialist: B.Ketzeback
 Just as we were starting evening sky flats the filterwheel on the instrument
 locked up and would not turn. It was fixed in short order but evening
 twilight for flats was lost. After I focused the guider and we went to the
 first science target the guider camera controller crashed and required
 a power cycle to bring it back to life. The gmech controller also required
 a remap after this power cycle in order to find stars (most likely because
 the filter wheel position was lost and needed homing). I took morning sky
 flats and biases for the observer upon request.

     used is north=0 degrees, east=90 degrees.  The dust count is
     particles > 1u per 0.1 cubic feet.
