(* means a trouble report has been issued or appended to)
The telescope was not opened this evening due to high dust counts, overcast
skies, rain, fog, and high humidity.
Xiaohui Fan waited to observe for the first half of the evening, but could not
due to weather.  Nichole King also waited for the bad weather to clear, but it
did not.
I could not observe for the Lens Monitoring run due to the weather, and the
guider tests were also postponed until the weather clears.
