                ------------- ACTIVITY LOG --------------
 Observing Specialist: J.Dembicky
 Again I held off opening tonight due to a storm to our south/southwest.
 It completely clouded up by about 21:30 and the rain sensor went off
 around  22:10.  It appeared to clear around 23:00 but by the time I
 opened (23:15) and got the telescope focused the clouds came back and
 made me nervous about being open, so I opted to play it safe and keep
 the mirror covers closed (although I left the building open).  The clouds
 stayed and my 1st half observer gave up around midnight.  I did the
 instrument swap around 00:20 and also closed the dome, just to be safe.
 Around 02:20 the clouds quickly moved out, although I had a hunch it
 could be a sucker hole.  I decided to open and at least get DIS focused,
 the re-evaluate the conditions.  I didn't get finished focusing before
 the clouds moved overhead again, as I suspected.
 Tom gave up around 03:20 as he wasn't going to have enough useful time
 and the clouds were still over polaris.  Of course it started to clear
 out shortly afterwards.
 The clear sky gave way to the clouds again around 04:00.  I did get a
 couple engineering tests done with the DIS slitviewer that Craig had
 requested (and manage to find a bug or two).
 John Barentine logged in remotely and I had him try running (taking some
 science for his UC04 program) while I played around with testing various
 things with the new TUI.  It is much easier to test (and make fail) while
 you have an observer on the other end who has been donated time.  We
 found a couple items and clouds really didn't allow much in the way of
 science, so I chalked all the time up to EN01 as that really was what it
 came down to.
 Tom would have got nothing useful with these clouds, for his program, but
 we were able to use the time for engineering and get some useful
 information even with the clouds.

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