              ------------- ACTIVITY LOG --------------
Observing Specialist: R.McMillan
Mostly clear all night with moderate seeing.  The second half observers had a slow internet connection, apparently near the APO end because they were all in different locations.  It made some field identification difficult but didn't prevent observing.
