                  ------------- ACTIVITY LOG --------------
 1st Half Observing Specialist: Camron Hastings
     Opened at 17:30 to begin cooling and started flats for the lens program
under clear skies. Tonight I noticed that the MC would not talk to the
echelle when I issued commands to check temp, but the ICC was communicating
with the echelle. I discussed this with Craig and we have an idea as to the
problem and will try and implement tomorrow so that we will not impact
observing tonight. All else was working well.
     Tonight I tried out a new script for the lens monitoring project with
great success. Seeing improved to subarcsecond soon after twilight end. The
guider was quite unhappy with this. I tried using the 'goodseeing' routine
Russet developed, no luck, it still ignored the guide star. I tried to rebin
to 2x2 with no luck. I defocused it somewhat with some luck.
 2nd Half Observing Specialist: Russet McMillan
 Second half was mostly clear, although some very thin clouds showed
 up starting around 02:00.  Seeing was generally very good (0.6-1
 arcsec), except at very high airmasses.  The guider did have some
 trouble identifying stars under the best seeing conditions, but
 usually kept going with a moderate amount of babysitting.  Aside from
 that, there was no trouble at all.
