The first half of the night was clear, with a few clouds on the horizon.  Patchy clouds rolled by around 11pm, then again starting at around 1am.
Observations were made during this time but with clouds occasionally interrupting exposures.  Clouds covered most of the sky from 2:30 am until twilight.
Around 3:15 am, there was a slight sprinkle that lasted for roughly 5 to 10 minutes.  It seemed to have started just after I had closed the mirror
covers and was in the process of closing the dome.
