  "body": "The IceCube Collaboration (http://icecube.wisc.edu/) reports:\n\nOn 2020-06-20 at 03:03:32.282 UT IceCube detected a track-like event with a moderate probability of being of astrophysical origin. The event was selected by the ICECUBE_Astrotrack_Bronze alert stream. The threshold astrophysical neutrino purity for Bronze alerts is 30%. This alert has an estimated false alarm rate of 2.321 events per year due to atmospheric backgrounds. The IceCube detector was in a normal operating state at the time of detection.\n\nAfter the initial automated alert (https://gcn.gsfc.nasa.gov/notices_amon_g_b/134207_33533447.amon), more sophisticated reconstruction algorithms have been applied offline, with the direction refined to:\n\nDate: 2020-06-20\nTime:  03:03:32.28 UT\nRA: 162.11 (+0.64 -0.95 deg  90% PSF containment) J2000\nDec: 11.95 (+0.63 -0.48  deg 90% PSF containment) J2000\n\nWe encourage follow-up by ground and space-based instruments to help identify a possible astrophysical source for the candidate neutrino.\n\nThere are no Fermi 4FGL or 3FHL catalog sources in the 90% uncertainty region. The nearest gamma-ray source in either catalog is 4FGL J1041.0+1342  at RA: 160.27 deg, Dec: 13.71 deg (J2000), 2.51 deg away from the best-fit event position.\n\nThe IceCube Neutrino Observatory is a cubic-kilometer neutrino detector operating at the geographic South Pole, Antarctica.
