Kurt, you've discovered the advantage of observing on a hillside. Wind, usually upslope but sometimes downslope, can create a laminar flow that will actually improve seeing, relative to a site with still air. This is a large-scale manifestation of the same effect that blowing air across the face of a telescope's primary mirror has. The boundary layer is disturbed. Fast-moving air has a much smaller effect on resolving fine detail than slow-moving boundary-layer disturbances caused by temperature differentials. You may not have noticed any breeze at ground level, but trust me, it was there if the seeing was better than average. You were near the same place where I and friends used to fly "slope-soaring" R/C sailplanes some 25 years ago. Great report. I spent the afternoon finishing-up my vegetable garden planting for 2007. Ended the day with an ice-cold Provo Girl and feeding stale bread to the mallard pair that enjoy a daily rest in our backyard. Nice day.

Prominences could still be seen after 3pm when the Sun is at a lower altitude - a unusual level of seeing.
