  "body": "The AMON,  IceCube, and HAWC collaborations report:\n\nThe AMON NuEm stream channel found a coincidence alert from the\nIceCube online neutrino selection + HAWC daily monitoring analysis.\nThe analysis looks for IceCube neutrino events -mostly atmospheric\nin origin- around the position and transit time of a HAWC cluster of\nlikely gamma rays, as identified in the integrated observations from\na single transit, in this case having a duration of 6.06 hours.\n\nThe HAWC transit interval starts from 2023/09/27 01:10:10 UT  to\n2023/09/27 07:20:17 UT\n(End of the HAWC transit time)\n\nThe location of the coincidence is reported as\nRA (J2000): 331.92 deg\nDec (J2000): 12.44 deg\nLocation uncertainty (50% containment): 0.13 deg (statistical only).\nLocation uncertainty (90% containment): 0.24 deg (statistical only).\n\nThe false alarm rate (FAR) of this coincidence is 3.9 per year.\nWe encourage follow-up observations of the alert region contingent on\nthe availability of resources and interest, given the quoted FAR.\n\nAMON seeks to perform a real-time correlation analysis of the\nhigh-energy signals across all known astronomical messengers.
