After three weeks of no observing due to cloudy weather, finally had a night out last night. Transparency was poor; in fact there were marine clouds to the east and south, which seemed to threaten to take over at any moment, but somehow I remained in a bubble of relatively clear air. Seeing was choppy so I used my 8-inch mask throughout. I observed from 9pm to about 1am, when I became too tired to continue (and the pain in my injured neck was too bothersome). It was chilly but I wore a warm jacket, and there was moderate dewing.
