              ------------- ACTIVITY LOG --------------
Observing Specialist: R.McMillan
Weather was photometric all night, with occasional borderline wind gusts and borderline dust.  Seeing was variable, good first half and less good second half.
The first observer made a time zone conversion error and didn't log in until after the end of twilight.  I had the instrument all focused and ready to go and everything went smoothly after that.
