              ------------- ACTIVITY LOG --------------
Observing Specialist: A.Bradley
We started out with a big thunderstorm, and battled humidity all night.
Seeing wasn't terrible, but not stable.  It was difficult to get a good focus.
When moving between Bay 2 and 1, the gratings ended at slightly off positions, 8 and -5.  I gave the adjustments in the gratings file, and all of the detents looked ok, but that edit only improved things a small amount.  MAybe the turret belt is too tight?  Definitely not the same as last night, though.
