The third night of this little campaign brought more weather challenges. The first half of the night was usable for the most part, despite partly cloudy skies. Nine blazars were observed, though clouds and cirrus slowed progress for a few targets. The seeing was often poor, coming in at around 2 arcsec, although the first hour of the night boasted sub-arcsecond seeing.
At about 0100 local time, the humidity rose and the mountain formed a cloud
cap. By 0300, the observatory was in dense fog. Who knows what will be
in store tomorrow for the last night of the campaign?
