              ------------- ACTIVITY LOG --------------
Observing Specialist: J.Dembicky
The ARCTIC diffuser did not seem to want to move out of the way when I tried to focus ARCTIC.  This was OK since the observer wanted the diffuser in but I was not able to get a focus measurement with the diffuser in place.  I will test the diffuser when I remove the instrument.
We were plagued with on and off local clouds for 2nd half.
My observer was taking dome cals in the moring so I could not unmout ARCTIC to test the diffuser movement.
