A remarkably intense auroral band flooded the northern night with
shimmering colors on December 7.
sequence captured here was made with a camera
fixed to a tripod under cold, clear skies near Ester, just outside
of Fairbanks, Alaska.
Left to right, spanning a period of about 30 minutes, the panels follow
changes in the dancing curtains of northern lights extending
of over 100 kilometers in a band arcing directly overhead.
The panels span 150 degrees vertically, covering about 500 kilometers of
aurora laying across the sky from edge to edge.
The auroral activity was triggered by a moderate level geomagnetic storm,
as a high speed solar wind stream buffeted
planet Earth's magnetosphere.
