                               ACTIVITY LOG
The telescope was opened at 18:45.
Patricia Knezek was the observer for JH02.  This was her third evening on site.
Comments:Things went pretty smoothly tonight, after a late start at dusk
because
the eyelid on the nasmith port kept closing.*  The weather was great,
and the guider worked well when it could find a guide star within its
tiny field of view!  Otherwise, Tia introduced me to guiding off the
slit viewer, which works well.  Thank goodness for the slit viewer!
I observed for the Lens Monitoring run, 0957.  No problems, seeing was 0.98
arcsec.
Michael Strauss and Xiaohui Fan were on site to observe for the PU02 program.
Comments: An excellent night of clear skies and good seeing.   Everything
worked fine for our long exposures,
and we got good data.   We just wish we had a red chip that wasn't so noisy;
the blue chip side looks
great.   and puts the red side to shame.
