This nice sun halo (properly called a 22º halo) that appeared directly above the IceCube Lab meant that there were ice crystals in the atmosphere, one of the reasons that the skiway wasn’t seeing enough action last week. Some folks were all packed up and ready to leave, but no plane was there to take them away as the flight schedule kept being pushed back due to weather. Such is life at the South Pole.

Last week at the Pole, the first two planes of the season arrived (and then departed again—both had short stays). They were small planes, but still, any plane landing at the Pole these days is an exciting event after the long, dark, quiet winter.

Although the South Pole is essentially a desert, a hefty accumulation of snow occurs on and around the buildings there each winter. How is that? Well, it’s the wind. Antarctica is a windy place—even with so little precipitation, it features some extraordinary blizzards thanks to strong winds.

A recent work by Markus Ahlers, a John Bahcall fellow at WIPAC, has shown that fluctuations in the cosmic-ray dipole anisotropy can be understood once the local magnetic field and the presence of local CR sources are taken into account.

With the sun out, you can see again—and here we see all the flags surrounding the marker at the ceremonial pole. They didn’t just appear out of the darkness, though. They were recently replaced for the summer season after being taken down for the winter.

Flags serve an important purpose at the Pole, marking out routes between places for when visibility is poor. Here you can see the IceCube Lab (ICL) in focus behind a flag line in the foreground.

Up, up, and away. That’s a NOAA balloon launch shown in a time-lapse photo—pretty nice! Last week at the Pole was all about the camera.

A new temperature record for 2016 was set at the Pole last week—a low of –107.9 °F. The extremely cold temperatures didn’t stop one station inhabitant from climbing the outdoor staircase is short sleeves.

This summer, two students worked with WIPAC throught the Research Experiences for Undergraduates program at UW–Madison. We have talked to them to learn about what brought them to Madison and what they are now taking back with them.

One unique aspect of living at the Pole for a year is experiencing only one sunset, at the equinox in March, and only one sunrise, which occurs in September, while you’re there. Since the sun rises just once during the whole year, it’s kind of a big deal. It’s also a slow process, with daylight increasing little by little as the sun’s arrival nears.
