              ------------- ACTIVITY LOG --------------
Observing Specialist: R.McMillan
Variable clouds made it hard to plan observations but mostly it didn't prevent them.  There was a period in the middle of the night when the dome stayed open but no one was getting anything, so I did count that as lost to weather.  But although it was a struggle, some pretty good spectra were obtained and everything worked reasonably well.
