  "body": "The IceCube Collaboration (http://icecube.wisc.edu/) reports:\n\nOn January 24, 2019, IceCube detected a track-like, very-high-energy event with a high probability of being of astrophysical origin. The event was identified by the High Energy Starting Event (HESE) track selection. The IceCube detector was in a normal operating state. HESE tracks have a neutrino interaction vertex inside the detector and produce a muon that only partially traverses the detector volume, and have a high light level (a proxy for energy). An inspection of the event does not reveal any feature to rule out this event as an astrophysical candidate.\n\nAfter the initial automated alert (https://gcn.gsfc.nasa.gov/notices_amon/9759013_132077.amon), more \nsophisticated reconstruction algorithms have been applied offline, with the direction refined to:\n\nDate: 2019/01/24\nTime: 03:43:54.79 UT\nRA: 307.40 [-0.9,+0.8] (deg  90% PSF containment) J2000\nDec: -32.18 [-0.7,+0.7] (deg 90% PSF containment) J2000\n\nWithin the 90% containment region there are no 3FGL or 3FHL objects. We encourage follow-up of this alert by ground and space-based instruments to help identify a possible astrophysical source for the candidate neutrino.\n\nThe IceCube Neutrino Observatory is a cubic-kilometer neutrino detector operating at the geographic South Pole, Antarctica.
