SOLAR WIND SPARKS ARCTIC AURORAS: This weekend, Earth is inside a stream of solar wind flowing from a large hole in the sun’s atmosphere. This is causing bright auroras to dance around the Arctic Circle. Last night in Rovaniemi, Finland, photographer M-P Markkanen witnessed this astounding display:
“I was driving home after midnight when, all of a sudden, I noticed in my rear mirror that the sky had just exploded into incredibly fast moving curtains of green, pink and white,” says Markkanen. “I had to stop the car on the side of the road, and soon I got to witness the most incredible aurora show I’ve ever seen! It evolved into fast pulsing and flashing coronas that lasted for an hour or so. It looked like the whole sky was a big ember on a camp fire! Warmed me up a bit although I felt quite cold by then. It was just mind blowing.”
Arctic sky watchers should remain alert for auroras on Saturday night as the solar wind continues to blow.
