Auroral curtains in twilight on March 14, 2018 from the sea north of Tromso, Norway. The curtains are showing a purple tinge to the background sky, likely from scattered blue sunlight mixing with the red oxygen colours. The Big Dipper is at upper left; Orion is at far right; Leo is left of centre, in a view looking south. | |
