                  ------------- ACTIVITY LOG --------------
 Observing Specialist: B.Ketzeback
 Moderate to high winds from the east resulted in very poor seeing conditions
 all night with excursions upwards to 6.0 arcseconds. Second half the windgusts
 seemed to decline in amplitude and seeing settled between 2 and 3 arcseconds.

     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.
