                ------------- ACTIVITY LOG --------------
 Observing Specialist: R.McMillan
 I opened at about 22:00 and got data for two pointing models with
 the telescope moving in opposite directions, which showed excellent
 repeatability compared to each other and good consistency compared
 to last night.  With clouds starting to move in, I got an Agile
 instrument block.  There were radar returns nearby and I didn't
 think I could get good tracking test data through the clouds, so I
 closed the dome at 01:30, but after that I did some in-dome
 instrument testing so I only counted part of the morning as lost to
 weather.
