Observing Specialist: deglman
The outer PMSS desiccant canister showed pink in the window during the
afternoon checkout.*  The problem reporting page was not accessible.*
Opened at 19:10.  Had another Grim hang up tonight.*  Restarted the
instrument mac and the mc (meaning Remark also).  DIMM had problems
finding Polaris.  It was about one degree off in the finder when I
centered it up.  The maximum seectrl SEARCH radius is 30 arcminutes.
Tycho once again dumped the night log and did not bother to autosave it
before hand, even though it indicated that had been doing so.*
Reconstructed from memory.  Had some problems switching Grim to f/10.  It
seemed to take a few minutes for the images to settled down.*  A
relatively uneventful second half.  Had a few minor NA2 rotator run aways
of only a few degrees.  Closed at 06:30.  "Dome" flats were done off the
mirror covers, then darks were obtained.
