              ------------- ACTIVITY LOG --------------
Observing Specialist: T.Rudyk
Shift started out with fog, trapped in a cloud again. It cleared up around 03:00 but the humidity remained too high to open.  No observing was accomplished.  In lieu of the snow program, which could not be run due to numerous power flickers, the dome was rotated 90 degrees every hour or so.  There may still be snow on the roof, though, as the winds did not exceed ~20mph.
