Weather Report for July 25, 2014


In an unusual move, the monsoon went into far western Arizona, leaving Kitt Peak with clear, though hazy/dusty skies. For the first night of this campaign, a full night of observing was available without any interference by clouds. Much spectropolarimetry as well as spectrophotometry were obtained. The seeing was reasonable right at the start of the night (1-1.5 arcsec), but for the next several hours, the seeing was 2-3.5 arcsec. The seeing improved to nearly 1 arcsec during the last hour or so of the night.
