Weather Report for June 20, 2015

There was some light, scattered cirrus during the first hour of the night. Smoke from distant wildfires to the north of the observatory was again evident during evening and morning twilight (therefore, smoke was presumably in the sky throughout the night). These minor irritants were not much of an issue and it was a very productive night of observing. The seeing was much improved over last night and generally 1-1.5 arcsec.
