Observing Summary:

High humidity was the theme for tonight.  The humidity was
63% at sunset and steadily increased, topping out at 83%
at 9pm, and then decreasing.  But then it started to rise
again, reaching 85% and forcing me to close up shop at 1:50am.
At the very end of the night, the humidity decreased below 85%,
but there was less than 1 hour left for observing, so I did not
open again.  It was also windy, but there were no clouds.  Five
program objects were successfully observed.
