                ------------- ACTIVITY LOG --------------
 Observing Specialist: R.McMillan
 We were getting vestiges of Emily during the day.  Clouds thinned
 out around sunset, so we opened on time, but we were barely able to
 focus and then the clouds thickened.  Since the observer got no
 science, I didn't count any of the time as usable.  Second half we
 had a few sprinkles (which didn't trigger the rain sensor until
 several minutes after I closed the cloudcam), and more clouds.  I
 did some planning for Saturday with the Apollo personnel and worked
 on catching up with error-checking night logs.

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