GCN Circular 33870

The IceCube Collaboration (http://icecube.wisc.edu/) reports: On 2023-05-24 at 11:09:36.24 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 average astrophysical neutrino purity Bronze alerts is 30%. This alert has an estimated false alarm rate of 4.25 events per year due to atmospheric backgrounds. The IceCube detector was in a normal operating state at the time of detection. After the initial automated alert (https://gcn.gsfc.nasa.gov/notices_amon_g_b/137971_11526243.amon), more sophisticated reconstruction algorithms have been applied offline, with the direction refined to: Date: 2023-05-24 Time:  11:09:36.24 UT RA: 318.43 (+3.12 / -2.59 deg  90% PSF containment) J2000 Dec: +2.84 (+2.55 / -2.43 deg 90% PSF containment) J2000 We encourage follow-up by ground and space-based instruments to help identify a possible astrophysical source for the candidate neutrino. Two gamma-ray sources listed in the 4FGL Fermi-LAT catalog are located within the 90% uncertainty region. The sources are 4FGL J2110.3+0404 and 4FGL J2109.6+0440 located 1.50 and 2.10 deg away from the best-fit position, respectively. The IceCube Neutrino Observatory is a cubic-kilometer neutrino detector operating at the geographic South Pole, Antarctica.
