                ------------- ACTIVITY LOG --------------
 Observing Specialist: B.Ketzeback
 Intermittant cloud cover first and second half. No time lost due to weather
 however. Guiding seemed to be smoother tonight. Less bounce seen and no
 drift. First half observer informed us that our network problems may have
 been due to a scheduled weekend power outtage down on campus. The night
 staff had not been warned that this was to occur. Because of the trouble
 with the network the second half user (the first off-site observer this
 weekend) had serious and repeated connectivity problems with her TUI
 dropping connection. Usually after a few minutes she could reconnect however
 at 0430, she could no longer reach the site. Finally she called me and I
 the rest of her data for the night. I estimate that about 30 minutes
 was lost to this problem.
