The majority of tonight's time was lost due to weather, usually high
humidity, but on one occasion, snow being blown ahead of an approaching
cloud front.
Doug Hoard observed with Grim, but did not obtain any useful data as
his time was limited to less than a half of an hour under marginal
conditions.  Due to snow that was to the north east, south, and
variable conditions, I was conservative on re-opening.
Brad Holden observed for the second half of the night with Spicam.
Again, humidity prevented his observations for the majority of his
time though one useful hour was obtained at the end of his time.
Twighlight flats were not possible due to weather moving in and
high humidity.
The ftp transfers continue to be slow.
