The night began as did the previous night: photometric skies and fairly good
seeing of about 1.5 arcsec.
However, debris clouds from afternoon build ups were not far from the
observatory to the south and east.
These clouds started to seriously affect observations by midnight.
Observations continued until the end of the night, but the going was very
slow with frequent, relatively short stops in the data taking caused by
thicker patches of cloud.
Only a little over half of the number of objects could be
observed than during a clear night of the same length
and much less spectrophotometry could
be obtained.
