South Pole Auroras

On July 5th, a geomagnetic storm sparked brilliant auroras directly above Earth's south pole.

Such a remote event is seldom recorded and publicized, but this time a researcher at the Amundsen-Scott South Pole Station was outdoors at just the right moment to capture the display.

His photos, along with a description of what it's like to take pictures when the temperature outside is -84 F, are featured in yesterday's edition of http://spaceweather.com
