              ------------- ACTIVITY LOG --------------
Observing Specialist: R.McMillan
Mostly clear all night long.  Some variable seeing but never too horrible.  Everything worked well.
I changed the zeropoint focus values for Tspec and NICFPS after tonight's
measurement.  Hopefully they will be in better agreement with other instruments now.
