Good morning Listees and Listoids, Last night Linton also wrote:
"There were large, shifting areas of pink and purplish colors, rather than the green which is apparently more common." Sky & Telescope, July 1981, p. 86: "Auroras above 240 km (150 miles) are mainly red from light given off by oxygen atoms. Between 100 and 240 km it is the green light from oxygen that is most apparent, and below these altitudes the red and blue light of nitrogen atoms is strongest. It is likely this latter source was responsible for much of the April [1981] display."
