Another long struggle with moonlit cirrus clouds tonight. Fortunately,
Kitt Peak was on the correct side of a sharp cloud boundary to its west
for most of the night, although most observations were made through
thin cirrus. Clouds forced an end to operations at 0300 local time.
The seeing was 1.2-1.5 arcsec. Nearly 15 blazars were observed (including
multiple observations of CTA102), but little of the polarimetry will be
accompanied by photometry.
