              ------------- ACTIVITY LOG --------------
Observing Specialist: A.Shelden, R.McMillan
Many power flickers in quick seccession, 17:08  Had to reset the mirror
covers.
Opened in a break in the clouds.  However about an hour later the clouds
had filled in.  There was nothing threatening about them, so we tried to
push through them.  Got data during the following times:
18:52-19:41
21:45-22:00
22:30-23:04
Wind was a bit strong.  Stayed within bounds for the most part, with a
handful of gusts in the red.  Kept an eye on the pmss for signs of
trouble, but all seemed ok (although a bit noisy).
During Tspec cals for NM09, the enclosure interlock tripped even though
there was no power flicker while motors were stopped.  Reset was quick, it
was just a mystery why it tripped in the first place; the controller was
fine.
During the NM09 observations there was one strong wind gust.  As the next
observers were slewing to their first target, two more strong gusts
appeared so I closed the dome.  Very high winds, high dust, and high
humidity rounded out the morning, and we never reopened.
