TITLE: GCN CIRCULAR NUMBER: 40730 SUBJECT: IceCube alert 141029_8144692 retraction DATE: 25/06/14 15:31:50 GMT FROM: Erik Blaufuss at University of Maryland, College Park blaufuss@umd.edu
The IceCube Collaboration (http://icecube.wisc.edu/) reports:
On 14 June 2025 at 09:14:04 UT IceCube issued an alert (https://gcn.gsfc.nasa.gov/notices_amon_icecube_cascade/141029_8144692.amon) reporting the detection of a neutrino cascade candidate event with a high chance of being of astrophysical origin. Upon further examination by the IceCube collaboration, the event was found to be from a non-standard configuration that was intended to be excluded from alert selection
At the time of this alert, the detector was operating normally but taking data in a non-standard test configuration. Normally, these periods of operation are excluded from generating alerts, but an alert message was significantly delayed in transit from the detector site at the South Pole and arrived after resuming normal operations 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
