General information
GRB 260522A triggered Fermi/GBM at 02:15:08 UT on 2026-05-22 and is described as a likely short GRB, with high-energy emission also detected by Fermi-LAT. The best reported sky position is from LAT at RA,Dec = 346.67, 9.66 (J2000) with a 0.55 deg (90%) statistical error radius.
Wavelength coverage
- Gamma-ray (keV–MeV): Fermi-GBM trigger and spectral/fluence measurements reported.
- High-energy gamma-ray (MeV–GeV): Fermi-LAT detection with >100 MeV flux and photon index reported.
- Optical: GOTO and MASTER-Net observations reported only upper limits (no credible transient found).
