Two(!) thunderstorms hit the observatory this afternoon and the first half of the night was lost to the mess that they left behind in the sky. The sky cleared quite well between midnight and 0100 local time. Ten blazars were observed in mostly clear conditions with seeing that degraded from 1.3 to 2.5 arcsec as the night wore on. More clouds ended the night just before morning twilight began.
This night ends a highly successful monitoring campaign, which was the best
September campaign experienced in at least 3 years. Campaign 65 will
start in late October at the Kuiper Telescope on Mt. Bigelow, Arizona.
