This is the second highest-energy neutrino ever observed, with an estimated energy of 1.04 PeV. IceCube physicists named it Bert. Twenty-eight events with energies around and above 30 TeV were observed in an all-sky search, conducted between May 2010 and May 2012, for high-energy neutrino events with vertices contained in the IceCube neutrino detector.

The IceCube Laboratory at the Amundsen-Scott South Pole Station, in Antarctica, hosts the computers collecting raw data. Only events selected as interesting for physics studies are sent to UW–Madison, where they are prepared for use by any member of the IceCube Collaboration.
