Weather Report for September 23, 2014

The daily afternoon thunderstorms set up farther east of the observatory than on the previous day, leaving generally clear skies for the night. Except for a 1-hour period starting just after 0115 local time, when cirrus marred the sky, the night was clear. The seeing was not quite as good as on the previous nights, but the air was much drier and the seeing was still very good (0.9-1.4 arcsec).
