Two too brief periods of clear sky allowed me to collect luminance
data to replace poor luminance data collected in 2005.

Blinking the frames I selected for use was quite interesting as it
showed the frequent and rapid changes in both seeing and transparencey
that occur duiring the winter season. I was able to use about 60% of
the collected frames.
