Clear skies again tonight until a large batch of cirrus clouds ruined
the party at about 0330 local time. Up until then, the night was photometric
and purely polarimetric observations continued through various cloud
thicknesses until dawn. As with the previous night, the seeing was on the poor
side before midnight (2-3 arcsec), but improved to 1.5-2 arcsec for most
of the second half of the night.
