                ------------- ACTIVITY LOG --------------
 1st Half Observing Specialist: G.Saurage
 Storm rolled in just at sunset. High gusts (~40mph), dark clouds with
lightening all around, and rain sensor went off about 8:45pm. No real
accumulation of precipitation, but rain drops were blowing around.
Overcast and windy all first half.
 2nd Half Observing Specialist: R.McMillan
 The wind dropped a little after midnight, and a few holes started to
 appear in the clouds, but radar indicated another system approaching
 to our southeast.  We waited through thicker clouds, then opened the
 cloud camera for some thinner clouds, but radar was still iffy and
 humidity was rising.  A kewl lenticular cloud formed right over the
 ridgeline, which we don't normally see on this side of the
 mountains.
 I opened just before 04:00 so the observers could satisfy themselves
 that seeing was awful (it was).  We made some adjustments to
 pointing, watched the image jump and breathe and waver for a while,
 then closed at 04:40 as another system approached on radar.  We
 never even attempted ranging the moon.

     Note: the wind was coming from the azimuth listed.  The
     convention used is north=0 degrees, east=90 degrees.  The dust
     count is particles > 1u per 0.1 cubic feet.
