Arctic Dragon ? Carina Letelier Baeza (Chile) This impressive aurora, which seemingly takes the form of a dragon, was the result of a geomagnetic storm (level G2) generated by a coronal mass ejection. The photo was captured at the Arctic Henge, which was one of the only places in Iceland with clear skies that night. Taken with a Nikon D810A camera, 14 mm f/1.8, ISO 6,400, 2.5-second exposure Location: Raufarh?fn, Iceland, 25 February 2023
