Nitrogen Fringe
Green is the most common colour seen during auroral displays. It's produced when charged solar particles collide with oxygen molecules at altitudes of 100 to 300 km.
Sometimes the lower edge of an aurora will have a pink tinge, which is produced by ionised nitrogen at altitudes below 100 km.
On this November night, we saw it during an intense KP7 geomagnetic storm. Berufjörður in eastern Iceland.
