                ------------- ACTIVITY LOG --------------
 Observing Specialist: J.Dembicky
 I delayed opening due to weather around the site.  Finally around 20:45 I
 decided we could open, but if any signs of clouds appeared we would
 close.
 At about 21:50 the Echelle hung sending image to MC.  ICC rebooted. Data
 salvaged.
 I closed the mirror covers at 22:50 due to a passing cloud that I wasn't
 sure about.  Better safe than sorry.  I kept the building open but the
 mirror covers closed.  I re-opened at 23:00 after the threatening cloud
 passed.
 23:50 the MC died, restarted MC and all was happy again.  Clouds also
 rolled in about the same time and I closed a couple minutes later.
 Finally re-opened at 02:45, with caution.  I could see a cloud to the S
 with virga coming off from it but it appeared safe to open for the time
 being.  The clouds dissapated in about 30-45 mins and just left us some
 cirrus.
 No problems other than the MC crashing tonight (and a couple echelle
 hangs)

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