(* means a trouble report has been issued or appended to)
The telescope was opened at 17:00.  The WSMR group, assisted by Mark Marley,
tested the Amber camera on a variety of bright stars and the moon.
After a few attempts to locate an object, with quite a bit of trouble,
Charles Corson rechecked the tertiary position, but with no obvious error
found, we continued.  The pointing seemed to be fine after that.
I was preparing for Connie Rockosi's observing, and a storm rolled in from
the north bringing high humidity, snow, drizzle, high winds, and overcast
skies.  I could not reopen for the rest of the evening, as the weather was
completely unstable, with the humidity and clouds coming and going, and we
also received accumulation of approximately an inch of snow.
Latest forecast:(4:30am)
TODAY...A FEW MOUNTAIN PEAK SNOW FLURRIES THIS MORNING...OTHERWISE
FAIR SKIES.  NORTHWEST WINDS 10-15 MPH.
.TONIGHT AND FRIDAY...PARTLY CLOUDY.
