              ------------- ACTIVITY LOG --------------
Observing Specialist: A.Bradley
Heavy clouds rolled in at about 21:00, and became too heavy to guide through at 21:06.  We closed the mirror covers to wait it out--we did not close.  The clouds cleared just before 01:00, so we switched to JH02.  The rest of the night was clear, with seeing varying between 1.3" and 2.3" (despite the consistent numbers in this log).
