The band of clouds that started to move in at the end of last night took most
of tonight to move out of the area. The entire first half of the night
was lost to clouds. The dome was opened a little before midnight as the
thickest portion of cloud cover moved to the east of Kitt Peak, although
it turned into a real struggle to obtain successful observations for the
next three hours. Finally, the sky cleared nearly completely for the last
three hours of the night. In total, about a dozen blazars were observed
in clear skies and through cirrus clouds. Seeing varied between 1.5 and 2.5
arcsec.
