General information
GRB 260326A is a likely long-duration gamma-ray burst triggered by Fermi-GBM at 01:18:28 UT on 2026-03-26, with additional detections reported by GRID-11B and Insight-HXMT/HE.
Wavelength coverage
- Gamma-rays / hard X-rays: Fermi-GBM detection and localization; GRID-11B detection (30–2000 keV) with light curve; Insight-HXMT/HE detection with CsI detectors (
60–900 keV deposited energy, sensitive to >200 keV photons).
No observations are mentioned in the provided circulars for radio, optical/NIR, UV, soft X-rays, or TeV.
