              ------------- ACTIVITY LOG --------------
Observing Specialist: A.Bradley
The night was clear and beautiful, but full of pollen.  While we were open, we were productive.
Played with the new dcam.  Fritz got the cooling fix worked out, we took new masks, and we tested limiting magnetudes.  There is a fringing pattern that only shows itself when the background is high.
Dis focus--no change.  Evaluated contamination--it's ok for now.
Collimation--very good, no change.
Apollo--checked out fine.
TCC--Russet and Russell worked on the gcam instrument block and a few other bugs.
Pointing was excellent, so we opted not to get the mirror pollenated.
Took spec darks all night.  Still unhappy.
