                ------------- ACTIVITY LOG --------------
 1st Half Observing Specialist: J.Dembicky
 Cloudy the first half with a few sucker holes passing thru.  Most didn't
 last much longer than 15 mins and it was not exceptionally clear while
 they lasted either.
 2nd Half Observing Specialist: R.McMillan
 We struggled through the clouds for a while, managing to get usable
 data on some bright targets but failing with anything halfway
 faint.  We stayed open long enough for twilight flats, but didn't
 get any science after about 03:30.  Everything worked well.

     Note: the wind was coming from the azimuth listed.  The convention
     used is north=0 degrees, east=90 degrees.  The dust count is
     particles > 1u per 0.1 cubic feet.
     Note: The Tower Dust counter appears to be down at this time
