Explanation: What
spooky planet is this? Planet Earth of course, on the dark and stormy night
of September 12 at Hverir, a geothermally active area along the volcanic landscape in
northeastern Iceland. Geomagnetic storms produced the auroral display in the starry night sky while ghostly
towers of steam and gas venting from fumaroles danced
against the eerie greenish light. Tonight, there is still a chance for geomagnetic storms triggered by recent
solar activity, so high-latitude skygazers should beware. And ghostly shapes may
dance in your neighborhood, too. Have a safe and Happy Halloween!
