The weather forecast continues to promise clear skies, but an amazing amount
of cirrus keeps flowing over Arizona. The cirrus clouds tonight were not
as thick as they were last night and work could continue all night long.
Nearly 20 blazars were observed through varying amounts of cirrus, with the
clouds being less of a problem after midnight than before. Almost
no photometry was attempted. The seeing was 1-1.5 arcsec.
