              ------------- ACTIVITY LOG --------------
Observing Specialist: R.McMillan
Another nice clear night with an even larger range of seeing.  Some of my focus measurements did not record successfully, but the seeing appeared to range from subarcsecond to more than 2 arcsec depending partly on the wind direction.
The second half observer had a late-rising target and so let the first half observer take some extra time.
