General information
IceCube-251225A is a track-like high-energy neutrino candidate detected by IceCube on 2025-12-25 20:14:06.80 UTC (Astrotrack BRONZE stream). The refined J2000 position is RA 297.42 deg, Dec 22.47 deg, and follow-up reports include IceCube time-window searches and a Fermi-LAT GeV gamma-ray search.
Wavelength coverage
- Neutrino: IceCube detected the alert event and searched for additional track-like events (none found) in 1000 s and 2-day windows.
- Gamma-ray (GeV): Fermi-LAT reports no significant (>5σ) new excess emission and provides >100 MeV flux upper limits for 1-day, 1-month, and ~17-year integrations.
No observations were mentioned in X-ray, UV, optical/IR, or radio bands.
