(* means a trouble report has been issued or appended to)
1st half Observing Specialist: K. Gloria
[From R. McMillan: Karen sent me her comments, and I accidentally
deleted them.  Here's what I know: there was a thunderstorm shortly
before sunset, accompanied by a sharp dust spike, but it was still
possible to open well before the end of twilight.  PU01 elected to
make a change in their plans and use DIS instead of GRIM, so they had
to absorb the extra instrument change time -- as it happened, that was
lost to weather anyway.  Pointing was mediocre but not remarkably bad.
We closed at 23:30 due to clouds.]
Observing specialist: R. McMillan
We opened for half an hour at 02:30 to try to take advantage of a hole
in the weather, but because of small clouds moving through it wasn't
even possible to get a good focus for GRIM before the heavy stuff
moved in again.
