              ------------- ACTIVITY LOG --------------
Observing Specialist:    J.Dembicky
Winds picked up around 22:30 and we closed about an hour later.  Clouds moved in around 00:30 and
the wind dropped below closure around 01:30, but the clouds didn't subside and kept us closed.
We opened at 04:10 just to close about 40 mins later.  Just enough time to focus and get two quick
std stars before the thick clouds moved back in.  We gave up at this point as it didn't look like
things would improve in the next 20-30 mins and not have enought time to do anything useful after
that.
