Horrible 3-4 arc sec seeing at the start of the night.  It improved around 21:30. with sub arc second seeing for 2nd half.
Rain sensor went off at 19:25, sky was clear and there was NO precipitation outside.  We turned it off and ignored it.
Clouds started getting worse around 03:00 and we finally closed at 04:10. Gave up at 04:45 due to clouds and weather.
