“On behalf of the operations group, I’m happy to report that as of run 127950 on 2016-05-20, 20:38:47 UTC, we have started the IC86-2016 physics run.” With these words, every IceCuber learned that we were entering a new year of data for IceCube.

Not a particularly busy or hectic week at the Pole—quiet punctuated by work, or work punctuated by quiet, depending on how you look at things. Now, depending on where, not how, you’re looking, you get to see all the action this time of year at the South Pole.

Under a sky lit by auroras, you can see the path through the Dark Sector, bright enough to make out the flag line for quite a ways into the distance. It’s a different story when there are no auroras or bright moon to illuminate things.

It’s aurora season at the South Pole. Two lone figures—both of IceCube’s winterovers—were out on the ice capturing images of the night sky. Although it’s a night sky, that tells us nothing about what time of day it is since it’s winter there and the sun remains down for about six months at a stretch.

The IceCube Collaboration has performed two independent searches for light sterile neutrinos, both with one year of data, searching for sterile neutrinos in the energy range between approximately 320 GeV and 20 TeV. IceCube has not found any anomalous disappearance of muon neutrinos and has placed new exclusion limits on the parameter space of the 3+1 model, a scenario with only one sterile neutrino. These results have been submitted today to Physical Review Letters.

IceCube winterover Mack’s Ecuadorian devil’s mask looks extra devilish under the red lights as he stands for a photo in his cold weather gear after coming in from outside.

IceCube winterover Mack van Rossem stands, with a full moon and the IceCube Lab (ICL) in the background, all geared up and ready to tackle IceTop measurements. Nice mask!

With the darkness of winter settling in, it’s time to cover the windows. It’s also time for winterizing outdoor equipment and vehicles. Although a large fleet of vehicles is needed for summer activity, most of them are left idle for the winter.

Today, at the APS April Meeting in Salt Lake City, Utah, scientists operating the High Altitude Water Cherenkov Observatory (HAWC) presented a new survey of the sky using the highest energy gamma rays ever observed.

It was a relatively tranquil week at the Pole, but not without its interruptions—April Fool's Day pranks among them. The waning light in the sky is beginning to lend a little eeriness to photos.
