    I love this message line. In the 70 I wired for the forest sevice in a wilderness area. We could use no motors. We contrived a device that was powered by a horse pulling a long rope coiled onto a drum. That in turn powered a chain saw blade. We almost had a chain saw. You all most have a GPS. If fact many point an shoot cameras now have GPS chips to Geo tag the photos. Still I love the concept. 

    Frank. Why do you suggest sun below to well above. I was told to bring the sun down. I suppose as long as you are consistent there is no problem. But as you know "back lash" is to be avoided. I am only an arm chair navigator (small boats and planes with lots of GPS) and ask out of ignorance.

    Greg, did you try taking a video with your camera attached? You could swing the arc more or less continuously starting with the Sun below the horizon and recording until the Sun is well above the horizon. Then review later to get that exact moment of contact. Maybe? And of course, you can include audio notes like a time check and your own impressions of when it all looks right.
