Observing Specialist: Frank Deglman
The outer PMSS desiccant canister showed pink in the window during the
afternoon checkout.*  The problem reporting page was not accessible.*
Opened at 19:05.  Enclosure dust went over fan limit about 20:00.  Had a
minor rotator run away on the first rotation (less than 20 degree
overshoot).*   Grim locked up once during the first half.  Reset things,
then it worked fine.  Had at least moderate cirrus for all of second half.
Got heavy enough at 04:30 to lose object, so closed up.  Did not reopen.
