              ------------- ACTIVITY LOG --------------
Observing Specialist: T.Sutherland

A big storm rolled in before sunset with lots of fog and rain, and a very ominous looking sky. Weather remained bad the rest of the night. 

DSSI is all packed up and put away.

No test slews tonight as humidity was too high to open mirror covers. 

Gave up just after 5am when a big fog bank rolled in.
