                ------------- ACTIVITY LOG --------------
 Observing Specialist: J.Dembicky
 A nice lightning storm to our West during twilight kept us closed until
 21:40, when it looked safe enough to open.
 I closed the telescope at 23:34 due to a storm to our N that might be
 heading this way (flow from the cloudcam showed N-S direction).
 I re-opened around 02:25.
 The DISslit guider again stopped taking images (got stuck) several times
 tonight.  The hub startNubs dcam fixed the problem each time.  The
 observer reported they were doing Ctrl+clicks (while it was guiding in
 manual mode) when it locked up, perhaps a clue?

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