Auroras of the autumn equinox
Increased levels of geomagnetic activity in the weeks around the autumn equinox often cause more intense displays of the aurora borealis, or northern lights. It’s thought that the tilt of the earth during both the autumn and spring equinoxes gives the phenomenon a boost by aligning the earth’s geomagnetic field with approaching solar winds. These carry supercharged particles into the atmosphere where they interact with oxygen and nitrogen to create the spellbinding displays of green and crimson light. Iceland’s countryside hotels like Hotel Ranga and Hotel Husafell are excellent options for viewing the aurora at this time of year. Another hotspot is coastal Swedish Lapland at properties including the Treehotel, Arctic Retreat and Brandon Lodge.
