                ------------- ACTIVITY LOG --------------
 Observing Specialist: B.Ketzeback
 Overcast skies until 21:00 when humidity spiked and stayed above the closure
 limit until 03:00. At this time radar returns and visible lightning storms
 to the east, in our radar blind spot, and to the south were enough to keep
 me from opening the remainder of the night. I spent much of the first half
 catching up on email questions from observers, gathering scraps of userful
 last minute knowledge from Craig Loomis on his last day at APO and paying
 careful attention to the weather. Second half was spent watching the weather.

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