              ------------- ACTIVITY LOG --------------
Observing Specialist: R.McMillan
We had some thin to medium clouds and moderate seeing, but more
dramatically we opened late and closed once due to occasional smoke from a
nearby wildfire.  The particle counts spiked when the wind shifted through
the western direction; any wind direction outside the range 240-280 seemed
to be all right.  Over the course of the night the visible hot spots from
the ridge did diminish, especailly after the wind shifted to the
northeast; hopefully the fire can be put out on Friday before strong winds
arrive on the weekend.
