(* means a trouble report has been issued or appended to)
1st half observing specialist: Karen Gloria
The telescope was opened at 18:50 MST.  I delayed opening while I
decided what the weather would do.  We ended up with a lot of high
clouds, and wind.  The wind eventually forced us to close at 21:20
MST.
2nd half observing specialist: Russet McMillan
The wind dropped around midnight, permitting us to open for a while
starting at 00:45, but it soon rose again and I closed for at 02:55
for the remainder of the night.  The only problems were a hangup in
the connection with UW around 05:15 lasting just over ten minutes, and
and enclosure error when I tried to move the telescope to park
position in the morning.
Note: JH03 and UW03 swapped time slots in order to save on instrument
change time.
