Although I knew there was a slight chance it might get a bit windy, I decided to observe at the D.A.R.C. observatory because I needed the darkness to observe delicate galaxies from the Herschel 400 list in LMi, Com and CVn. After a short and uneventful 1h40m drive from the south bay, I arrived at the D.A.R.C. observatory. The thermometer in my car was clocking 92F! The wind, coming from the north, was not terribly strong, so I proceeded to setup my equipment.

Early on, the seeing was pretty good, but the transparency was just about average as indicated by the light domes from Fresno, Hollister and Los Banos. The seeing remained good for the entire night, and the transparency got progressively better, yielding very decent images of deep sky objects. The wind almost completely disappeared and the temperature dropped from 92F to about 75F by 2am. It felt pretty good to observe in shorts and T-shirt. Only Rogelio was pesting against the warm and varying temperatures. It’s harder to cool a CCD when the air is warm, and the focus shifts as the temperature changes.

Since the night was short (about 4 hours of darkness), I kept pretty busy all night. I ended up logging 25 new objects from the H400 list, which makes it a good and productive night. Thanks again to Dr. Lee Hoglan for letting us observe on his property. Below is my log for the night. Cheers!
