              ------------- ACTIVITY LOG --------------
Observing Specialist: C.Gray
Arctic needed to be homed a couple times before FW 6 would home properly.
The BC1 eyelide (Apollo) didn't open properly on the first attempt, closing the mirror covers and reopening solved the issue.
The wind was high in the afternoon and I thought we wouldn't be able to open but it calmed right before sunset!  We were able to get some good shots of Venus even though it was through the clouds.  Knowing that Russet Moon-Shooter McMillan was coming onboard, the clouds parted for clear Apollo skies.  Not favoring a meager grad student, they returned in B half and annoyed the minion.  However, seeing was good all night.
In attempting to take exposures on my laptop logged in as CU02 (dawnflats), the exopsure was timing out.  I did an arctic init and lost a quad... But we were able to get sky flats.
