                ------------- ACTIVITY LOG --------------
 1st Half Observing Specialist: J.Barentine
 Thunderstorms roamed the region near sunset, after having dropped rain on
the site around 15:00.  I opted to remain closed due to the unsettled
conditions.  The clouds thinned toward the middle of the half but there
were still scattered radar returns in the immediate area.  The clouds
moved back in an rain threatened around midnight.  We did not open.
 2nd Half Observing Specialist: R.McMillan
 Clouds, dust, humidity, rain.  The guider looks a little better
 after being pumped, but tests on-sky will be needed for real
 certainty.

    used is north=0 degrees, east=90 degrees.  The dust count is
    particles > 1u per 0.1 cubic feet.
    Note: The weather tower dust counter is out of commision
