Northern Arizona astronomy: preliminary results of our solar eclipse trip | Williams-Grand Canyon News

FLAGSTAFF, Ariz. — My wife, Anne, and I travelled north to observe the recent solar eclipse, a trip we had planned for over two years. This was her first total (eclipse), having seen only the annular in 2012. It was my fourth total, plus three past annular eclipses.

For eclipse chasers, this is a paltry number since I know astronomers who have observed over 30.

So, we packed up our mobile observatory (17-foot trailer with telescopes and cameras) and headed north.

Luckily, we were able to find an agreeable farmer to let us stay on his land for two days where he even provided electricity for our equipment. We set up and pre-aligned the telescopes and cameras for advantageous solar tracking and prepared for the event.

On the morning of the 21st, as the partial eclipse phases proceeded, the lighting of the surrounding area took on an eerie dimming cast as if a storm were approaching from behind you. The breeze that was once lightly blowing stilled. Just before totality, the swallows came out, the cows got quiet, and the crickets began chirping, all events normally reserved for the early evening.

During totality, the horizon looked as if the sun had set about 45…
