Just as a point of reference Greg, this image was taken at 11.5 meters at Clayton last night. Seeing was around 7/10 and about usual for the site. Clouds present and a bit of pain but on great nights all you get is great seeing (my best DSO's show that) and very dewed on. Wind always drops at sunset except if there is a low coming in. High pressures present winds during the day but once solar heating has finished at dusk then the winds fall to nothing.
