(* means a trouble report has been issued or appended to)
Observing specialist: Dan Long
    We opened at about 21:00 after Denise finished her darks.  She had
a smooth run, with only a few clouds interfering toward the end.
    Doug's run was not so smooth.  Clouds and humidity were on the
increase, and I had to close only about half an hour into his run.
We did not reopen.

    The night started out looking very nice.  Almost no clouds,
reasonable humidity, and moderate east winds.  Clouds started
building after midnight and by 01:15 covered most of the sky.
Thunderstorms began developing nearby at about 02:00.  It began
raining shortly after 03:00.
