TITLE: GCN CIRCULAR NUMBER: 42172 SUBJECT: IceCube alert 141456_888784 retraction DATE: 25/10/08 23:19:08 GMT FROM: Erik Blaufuss at University of Maryland, College Park blaufuss@umd.edu
The IceCube Collaboration (http://icecube.wisc.edu/) reports:
On 8 Oct 2025 at 22:35:50 UT IceCube issued an alert (https://gcn.gsfc.nasa.gov/notices_amon_g_b/141456_888784.amon) reporting the detection of a neutrino candidate event with a moderate chance of being of astrophysical origin. Upon further examination by the IceCube collaboration, the event data was incomplete and clear classification of this event is not possible.
At the time of this alert, the detector was operating with several portions of the detector removed from data taking due to hardware issues. Normally, these periods of operation are excluded from generating alerts. We apologize for any confusion this error may have caused.
The IceCube Neutrino Observatory is a cubic-kilometer neutrino detector operating at the geographic South Pole, Antarctica. The IceCube realtime alert point of contact can be reached at roc@icecube.wisc.edu
