                ------------- ACTIVITY LOG --------------
 Observing Specialist: R.McMillan
 Frustrating weather.  The night started with borderline humidity, so
 I watched it for a while before caving in and opening.  As soon as I
 got focused, clouds moved in, so data taking was very frustrating.
 After the program change, humidity spiked and I closed.  Then the
 air warmed, but the dewpoint didn't drop, so I was reluctant to
 re-open with a cool telescope despite the technically acceptable
 humidity.  When I re-opened at last, the airtemp dropped (but the
 dewpoint stayed down), so I ended up being open at a higher relative
 humidity than I had previously been closed at.  Finally a
 combination of clouds and nervous-making humidity prompted the
 observer to quit a little early.
 The only problem aside from the weather was the outdated TUI version
 on the JHU observing computer.

     used is north=0 degrees, east=90 degrees.  The dust count is
     particles > 1u per 0.1 cubic feet.
