TWILIGHT GREEN: When the sun went down last night in Harstad, Norway, the colors of the sunset included blue, orange … and green. “With Arctic summer fast approaching, our nights are disappearing rapidly, but I still keep an eye on the sky in case auroras appear,” says Ross McLaughlin, who photographed the display:
“Despite low solar activity, the auroras were very bright. It’s a wonderful to see them mixed with the colors of the twilight sky. I’ll have to make the most of it while I can before the midnight sun arrives!”
This mixture of twilight blue + aurora green will continue to appear around the Arctic Circle for a few more weeks as the seasons change. Dates of special interest are April 9th – 12th when a wide stream of solar wind is expected to engulf Earth, possibly sparking 4 or 5 consecutive days of polar auroras.
