Light, scattered cirrus during the first 4-5 hours of the night. After that, the sky was clear. The temperature dropped by more than 15 degrees F during the night as a major winter storm approaches from the northwest. The multi-day storm is forecast to start in earnest by tomorrow night, so it is fortuitous that this campaign finishes tonight. With the large temperature drop, the seeing was generally poor, often 2-3 arcsec.
All in all, a
quite productive night to end Fermi/Steward Observatory campaign 33.
We'll try it again the day after Christmas. Happy holidays to all who
follow this program.
