Explanation: Gusting solar winds and blasts of charged particles from the Sun made the early days of October rewarding ones for those anticipating aurora. While out enjoying the stormy space weather from Toemmeraas, Norway, Trygve Lindersen recorded this picturesque apparition of the northern lights with a digital camera on October 6. From this perspective, the curtains of green light formed a ring which seemed to hover, wraithlike, just above the foreground trees. But the ring of light was actually 100 kilometers or more above the trees and the greenish glow produced by oxygen molecules interacting with energetic electrons and fluorescing near the edge of space. After days of enchanting auroral displays on planet Earth, the solar activity which triggered October's geomagnetic storms seems to have subsided ... for now.
