(* means a trouble report has been issued or appended to)
1st half observing specialist: K. Gloria
2nd half observing specialist: K. Gloria
The telescope remained closed tonight.  We had clouds and a brief
shower in the evening, followed by partly to mostly cloudy skies for
the remainder of the night.  We had a dust event around 23:00 MDT.
The sky became partly cloudy for a while late in the night, but the
humidity was too high to open.  The dewpoint sensor was reading 35%
relative humidity, but all other indicators (the 98% reading on the
hygrometer in the enclosure, the condensation on the cloud camera
window and railings) suggested the humidity was much higher.  Fog
and clouds rolled in around 5:00 MDT.
All of the observers were very patient, considering the weather
conditions.
