                 ------------- ACTIVITY LOG --------------
 Observing Specialist: J.Barentine
 Opened at 18:30 with mostly cloudy skies.  The clouds, a kind of thickish
cirrus with periodic sucker holes, persisted for several hours after
sunset.  We remained open while waiting out the clouds as radar gave no
indication of any rain in the region, but the soup was sufficiently thick
as to prevent science.  Toward midnight it thinned enough to get some
science photons, but the clouds remained throughout the night.  The later
hours were fairly clear, and the GFP crew got some good data.
 We ran a bit late in order to get some sky flats.

     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.
