                ------------- ACTIVITY LOG --------------
 Observing Specialist: J.Dembicky
 Dust limits prevented me from starting cooling before sunset.  Very high
 winds (Gusts 65+ MPH) kept us closed all night.  We had a power
 failure around 1:44 and the backup generators kicked in. The white stuff
 started flying around 03:15.
 When I went to close the telescope down for the night, the mirror covers
 were un-responsive (both auto and manual mode).  The eyelid worked fine.
 I kept the telescope at it's altitude and moved in azimuth to it's park
 position, mirror covers are now in manual mode but need immediate
 attention as I can't open them at all.  PR sent on problem.
