NOT AURORAS: For the past week, solar wind has been buffeting Earth’s magnetic field, turning skies around the Artic Circle beautiful shades of green. But not every green sky is caused by the aurora borealis. Last night, for example, pilot Brian Whittaker was flying 34,000 feet over the Atlantic Ocean when he witnessed verdant hues caused by a completely different phenomenon–airglow. Here is the picture he took from the cockpit window.
“A dark and moonless night away from all lights allowed a great view of this textured patch of airglow,” says Whittaker. “The illumination was faint, but it could be seen especially in contrast to the dark ocean abyss below!”
