Space Weather reveals a ‘green flash’ seen on the Sun. From the report:
GREEN FRAGMENT BREAKS OFF THE SUN (NOT REALLY): On July 12th, nature photographer Jim Young was watching the sun set over the Pacific Ocean west of Seaside, Oregon, when a green fragment broke away from the solar disk. His camera, a Canon 60Da, started taking pictures every 1/1000th of a second to record the event.
Here’s how Young described the green fragment:
“It was a green flash,” explains Young, “caused by refraction in the atmosphere over the Pacific ocean.”
The Pacific is a great place to find green flashes. Temperature gradiants in the air above the sea surface magnify tiny differences in the atmospheric refraction of red and green light, creating a verdant mirage.
There was a time when green flashes were thought to be fables, but now we know they are real. Jules Verne popularized the phenomenon in his 1882 novel “Le Rayon Vert” (The Green Ray). He described “a green which no artist could ever obtain on his palette, a green of which neither the varied tints of vegetation nor the shades of the most limpid sea could ever produce the like! If there is a green in Paradise, it cannot be but of this shade, which most surely is the true green of Hope.”
