                               ACTIVITY LOG
The telescope was opened tonight at 21:35.  Chris Stoughton was the observer
for UC05.
COMMENTS:Once the clouds cleared, we started taking the calibration star
exposure at 04:06 UT and then spent the rest of the time
taking low-resolution spectra of QSO candidates.  The telescope
and instrument worked well.  (I assume people are aware of the
high read noise in the DIS camera.)
The cloud camera stopped working during the night.
Thanks!
Ted Wyder was the observer for the second half of the evening.
COMMENTS:Everything went very smoothly tonight. The seeing was mostly
subarcsecond even in 20 minute exposures at H-alpha. There were no
problems with the pointing or guiding; both worked very well.  I only
had one small problem with spicam. During one exposure the "time left"
stopped updating. I aborted the exposure and tried to read it out but
nothing ended up in the file on disk. I then logged off of spicam and
logged back in again. That seemed to fix the problem.
--Ted
P.S. Tia, thank you for all your help tonight and for letting me use
the telecope through the twilight time.
