Creature Aurora Over Norway
Explanation: It was Halloween and the sky looked like a creature. Exactly which creature, the
astrophotographer was unsure (but
possibly you can suggest one). Exactly what caused this
eerie apparition in 2013 was sure: one of the best
auroral displays that year. This
spectacular aurora had an unusually high degree of
detail. Pictured
here, the vivid green and purple
auroral colors are caused by high atmospheric
oxygen and
nitrogen reacting to a burst of incoming
electrons. Birch
trees in
Tromsø,
Norway formed an also
eerie foreground. Frequently, new
photogenic auroras accompany new
geomagnetic storms.
