Spaceweather.com hat geschrieben:"This red rainbow is a mystery because the sun had set four minutes earlier and was well below the horizon," says atmospheric optics expert Les Cowley. "Furthermore, according to Nolf, there was no rain falling and none visible on local weather radar!"
Cowley and colleague Gunther Konnen, a meteorologist, may have an explanation: Thousands of feet above Nolf, the sun had not yet set. (Think about it: "If your flight has ever taken off shortly after sunset you will see the sun rising again as the airplane climbs," notes Cowley.) Somewhere off in the distance, they speculate, a mile-high rainstorm that somehow evaded the radar caught the reddened rays of the setting sun, producing the Bruno's 'bow.
