(* means a trouble report has been issued or appended to)
Observing Specialist: deglman
Opened late at 00:10.  High dust count at beginning of first half and
cloud cover til about midnight.
Had to do a SMALLSEARCH with DIMM for it to acquire Polaris.
Had two obvious Grim mac crashes (type 1 error), which necessitated
restarting.  Had two Grim failures which were not obvious computer
crashes, but restarting fixed the problem.
Grim focus drift may have been from 3.5m not being cooled until after
midnight.
Closed at 05:10.  Some Grim darks were done after closing.
