                ------------- ACTIVITY LOG --------------
1st half Observing Specialist: G.Saurage
Complete overcast at sunset. Low humidity despite very low local clouds.
NICFPS was not talking to tcc during check out tonight. The TUI gui was
blank. I exited and restarted the NICFPS-ICS on the ICC and then hub
startNubs nicfps, nicfps expose init, and hub startNubs nicfpsExopose.
Then things seemed to work.
19:55 opened when overcast skies became party cloudy and radar returns had
moved away. Still battling clouds on and off all evening.
2nd half Observing Specialist: R.McMillan
Second half continued with varying clouds and mostly poor seeing.
The clouds grew thicker as the morning progressed, and we couldn't
get anything for about the last hour before twilight.  Everything
worked well, including the slitviewer shutter, but the red grating I
failed to align a couple of nights ago looked so far off I decided to
stay late in the morning to improve on it.
