Dawn in the Middle of the Night
At about 2:40 am local time, I was at 35,000 feet over Bismark, North Dakota today. We were flying from Seattle to New York. I looked off to the north and saw that the sky lightened toward the horizon … almost like there was a distant dawn up there. Then I checked our latitude … around 47 degrees. That light probably was the reflections of the polar midnight sun in the atmosphere. On June 21st, there is midnight sun down to 67.5 degrees latitude. We were about 1200 miles south of that at 47 degrees.
As the morning wore on, and as we moved east and a little south (around the great circle route) the lightness increased and moved east until at about 5 am the sun rose over Ontario, Canada.
I’d never seen that before. It was pretty cool.
