The weather was very transient as moisture from the Southwest flowed over
the ridge and formed a line of cloud over the point, with relatively high
humidity. For the first half of the night, most of the observing occured
when the line moved sufficiently NE.  The majority of the second half was
lost due to high  humidity.
No data was obtained for the Turner Lens Monitoring program due to
high humidity and mostly cloudy conditions.
Paula Szkody observed for the first half.  After several attempts at
opening, we were able to have generally clear skies and good conditions
for the end of her time.  The changing conditions did however limit her
data to only a few good spectrum.
Brad Holden observed with SPICAM for the second half.  At roughly 01:15,
the humidity rose and we were forced to close.  Only one or two
useful science exposures were obtained.  We attempted to observe latter
in the night, but overcast conditions forced a quick closing as well.
By 5:00am, conditions had become worse and an early end to the drill was
called.
OBSERVER COMMENTS
Paula Szkody
"I have obtained about 11 spectra, 5 of which are good and the other
six are lower quality due to clouds but usable at some level"
Brad Holden
"no problems"
