                              ACTIVITY LOG
(* means a trouble report has been issued or appended to)
1st half observing specialist: Karen Gloria
The telescope was opened at 18:35 MST, after spectral cals were done.
The telescope pointing requires a 20 - 40 arcsec local correction after
large slews.  So, the pointing model is not so hot right now.
We had pretty good seeing, 1.1 arcsec most of the evening, and the
observing went very smoothly.  No problems of note, although Gordon
had one image come up with the incorrect exposure time in the header.
He has emailed Craig the details.
2nd half observing specialist: Russet McMillan
Second half was clear, and for the most part everything went smoothly.
Like Karen, I noticed that the pointing was pretty poor.  We had some
trouble with the slit camera, which bombed out several times with the
message "Error= TIME OUT, Command = Get Activity Status."  This
happened four times in the space of an hour starting at 01:45, then
cleared up by itself.
                            OBSERVER COMMENTS
G. Richards (UC01):
Quite productive.  Almost 25000 seconds of integration time on target
objects.  However, the network was about as bad as I have seen it in
years.  At the beginning of the night it was taking 11 minutes to
transfer 2MB.
