              ------------- ACTIVITY LOG --------------
Observing Specialist: A.Shelden
Night was completely cloudy.  The first half we were able to punch through without them being terribly threatening.  Around 12:30 I started to worry about some nasty clouds coming our way, and I closed at 01:05.  I did not reopen.
The echelle slitviewer was cranky tonight.  It would work for an hour or two, then would refuse to work again until slitty was rebooted.  During the last hour that we were open it required extra attention, because failed exposures would stop the guiding every few minutes.  I rebooted slitty 3 times throughout the night.
