Week 12 at the Pole

It was all about the sun last week at the Pole.  Weather conditions allowed the winterovers to glimpse the green flash as the sun finally set below the horizon. IceCube winterover Martin was in the right place at the right time to capture a photograph of it, above (and it wasn’t his first time). The […]

IceCube hosts 10-week virtual high school program with Marquette, SDSMT, WIPAC

Since 2013, the Wisconsin IceCube Particle Astrophysics Center (WIPAC) has hosted afterschool internships at least once a year to provide high school students in the Madison area the opportunity to work on real-world physics experiments. Through the internship, participating students have been able to meet working astrophysicists, learn computer-programming skills, and contribute to data analysis […]

New algorithm improves IceCube’s pointing accuracy

When the IceCube Neutrino Observatory sees a high-energy neutrino from outer space, IceCube researchers want to know where it came from. The unconventional “telescope” uses a three-dimensional grid of supersensitive light sensors buried under the ice at the South Pole to detect signals from these tiny, nearly massless fundamental particles, which rarely interact and can […]

Week 11 at the Pole

IceCube was stable last week, but the same can’t be said for the weather at the Pole.  They had high winds and mostly conditions of low visibility from blowing snow.  But there were a few brief moments where things cleared, and the sun was visible on the horizon.  The low sun highlights the texture of […]

Week 10 at the Pole

Last week was relatively quiet at the Pole. IceCube’s winterovers performed a few detector maintenance tasks and gave a tour of the ICL to South Pole logistics personnel.  Although winter is fast approaching and the sun is quite low, there is still plenty of daylight for taking outdoor photos.  Above we see the tour group […]

Week 9 at the Pole

The sun is getting noticeably lower in the sky at the South Pole. IceCube’s winterovers also note that it’s starting to get cold. Apparently, there’s “cold” and then there’s “South Pole cold.” Last week, the winterovers were busy outdoors, taking advantage of the lingering light to complete a round of IceTop snow measurements. They also […]

Week 8 at the Pole

Last week was relatively quiet at the Pole, offering a good opportunity to get out and reflag the flag line between the IceCube Lab (ICL) and the station.  They drill new holes and replace flags as needed to keep the line well maintained.  The flags are easy to see now while the sun is still […]
