                 ------------- ACTIVITY LOG --------------
 Observing Specialist: W.Ketzeback
Clear night, decent seeing. There were a few problems of note. The DIS red
camera operating temperature rose and fell several times in the afternoon
and early evening. It was not clear what the problem was caused by. Nicfps
remote pressure monitoring has stopped. There is no indication of the dewars
pressure, temperatures are holding steady however. The missing cable tray
cover was found, wedged underneath the cats eye mask and laying on the
primary mirror tonight when I opened mirror covers. There was one instance
of the echelle guider locking up, but that was quickly and easily recovered.
