A unique high-speed camera, designed to capture the fleeting effects of gamma rays crashing into the Earth’s atmosphere, will soon be on its way from the University of Wisconsin–Madison to Arizona’s Mount Hopkins.

A quiet week at the Pole for the detector, but he photos were just striking!  Here we have a nice shot of the ceremonial pole marker, with a bright moon situated just behind the sphere and flags flapping in the wind.

Even in winter, you can get an impressive halo—here it’s the moon.  Halos are caused by light interacting with ice crystals suspended in the atmosphere, and these circular halos, which can form around the sun or the moon, are called 22-degree halos.  They’re fairly common, seen more frequently than rainbows.

Last week was fairly relaxed at the Pole.  Some testing and troubleshooting with the detector, but all went rather smoothly.  As for the skies?  They were glowing.  And swirling, and shimmering.  The auroras sometimes swirl into shapes suggesting all kinds of things.

Although the sky is not yet dark, auroras appeared for the first time this austral winter. It was a good thing the detector ran well this week, because the winterovers were excited to experiment photographing the colorful night sky.

Each winter, once it gets dark enough, the station covers up all of its windows to prevent light from interfering with light-sensitive projects at the South Pole.  This year they decided to have a contest for the window cover art entries.
