An intriguing event has just been detected by the IceCube neutrino telescope!

This event has a 27.3% chance to be a neutrino of astrophysical origin. An event as significant or more should be produced by the background noise every 100 days in average.

Its energy is estimated to be around 107 TeV ¹ and its source is located with a 90% probability to be within a zone of 5.60 square deg ².

Is it the result of a blazar, a supernovae…? This alert has been sent to astronomers around the world so they can point their telescopes toward the source of this event. An other signal from a different messenger could allow to identify the source and understand the mechanisms powering this emission.

Complete set of information:

This event has been detected on 2023-01-22T03:50:02.000612 UTC (Coordinated Universal Time).
The algorithm estimates its source location to be around the following coordinates: right ascension = 17.6737 degrees, declination = 8.3807 degrees with a 90% probability to be within a disk of radius 80.1 arcmin and a 50% probability to be within a disk of 31.2 arcmin radius.
The uncertainty in the location of the event is based on statistical uncertainty only, not accounting for the systematic error which should be smaller. The estimated energy is 1.07660*10^2 TeV.
The background noise should produce an event at least as significant 3.62 times per year which leads to a probability of 27.30% that this event is a track-like neutrino of astrophysical origin.
