‘EQUINOX AURORAS: Last night, the sun’s magnetic field near Earth tipped south. This opened a crack in Earth’s magnetosphere. Solar wind poured in and fueled a magnificent display of arctic Northern Lights. Thilo Bubek took the picture not far from Tromsø, Norway. “We had some nice auroras,” he says, with what can only be described as Norwegian understatement.’
truly incredible!
