Mostly clear skies during the night, but there were brief episodes of
extremely thin cirrus. At just before 0200 local time, thick cirrus
built up over the Santa Catalina mountains and this hampered
observations for nearly 2 hours. Most of the photometry obtained
will be from the early portion night. Over a dozen blazars were
observed and the seeing was more stable than on previous nights of the
campaign (1.3-1.8 arcsec).
