In a study published today in the journal Physical Review D, HAWC announces a measurement of the cosmic-ray energy spectrum in the energy range of 10 to 500 TeV, bridging measurements at higher energy usually performed by ground based detectors and measurements at lower energy that previously had been conducted by detectors on satellites and balloons.
Since the winterovers spend a full year at the Pole, they get to fit in some R&R at McMurdo Station on the coast before the long stretch of winter isolation sets in. IceCube winterover Raffaela was off last week, after a two-day flight delay, leaving Johannes to hold down the fort on his own.
The IceCube detector started out the year with no major issues. Yay! But there was plenty of excitement in other arenas. Everyone gathered at the geographic South Pole for the unveiling of the new pole marker.
Last week was the third annual “Bermingman,” where folks go out into the berms to dig for buried treasure. Things are buried because of accumulated snow, not from actual snowfall but from storms and winds that blow in and deposit snow. In fact, just after the Bermingman, a huge wall of snow appeared on the horizon
If you didn’t have snow over your holidays, you can enjoy it vicariously through these South Pole pictures. They had all kinds of fun in the snow—sledding and tubing, snowmobiling, and running! The sledding worked up their appetite for celebrations.
Last week was a busy one at the Pole. A lot of holiday preparations and some visitors on station, including folks from Arctic Trucks, getting a station tour and giving tours of their vehicles.
