                ------------- ACTIVITY LOG --------------
 Observing Specialist: B.Ketzeback
 The monsoons continue. First half was busy opening and closing for waves of
 clouds and clear skies. Second half was mostly clear with some fast moving
 clouds between 0230 and 0330, however they were not threatening and we were
 able to stay open. The only problem to report was with the DIS instrument
 cart, which has become dangerous to operate when mounting the instrument.
 I filed a problem report.

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