(* means a trouble report has been issued or appended to)
1st half observing specialist: Dan Long
The telescope was opened at about 16:40.
Skies were clear or mostly clear until 23:00.
GRIM was found non-functional during the afternoon checkout.  The symptoms
are that ping, and all exposure functions fail.  We could however talk to
to the mechanicals.  The standard things of restarting the grimmac and
software didn't change anything.  The fiber box checked out ok.  The fibers
themselves were lossier than they should be ( Craig may have switched one
in the end ) but were not the problem.  Power cycling the instrument
resulted in no change.  Many thanks to Dale Sanford for helping check on
GRIM.
GRIM was declared down for the night and Tom Harrison decided to give Joni
Johnson the time using DIS.  Since hi-res was needed and not currently
loaded about 2 hours of their time was used to set up DIS.
2nd half observing specialist: Karen Gloria
The telescope was closed at 23:00 MST due to high humidity.  Fog
rolled in shortly thereafter.  The site was enveloped in fog for the
remainder of the night.
