# 3:00 AM, had some clouds in the past hour. Now clouds back to only really in the East. Wind has picked up quite a bit and wind screen was put on.

# 5:00 AM clouds remained on the horizon, wind stayed strong, seeing went up a bit, images went above 1 arcsec for a while but then came back down to around 0.9 on the QR.
