                              ACTIVITY LOG
(* means a trouble report has been issued or appended to)
1st half observing specialist: Loomis
The telescope was opened at 16:50 MST.  Dawn Leeber observed remotely
with GrIm2 for NM03.  *I had some trouble focusing GrIm2 in f/10
mode.  The focus kept changing wildly.  I didn't have any trouble
focusing in f/5.  No other problems to report.
We managed to miss just about all of the clouds this evening.
2nd half observing specialist: McMillan
During second half, we failed to miss all the clouds.  The telescope
was closed at 05:00 when the moon became invisible and the clouds
looked suspiciously low, but the weather was useless for observing
during much of the open time as well.
* We had a delay on startup due to problems establishing an autoftp
connection to NMSU, and a separate problem with GRIM refusing to take
images.
