General information
GRB 260519C is a long-duration gamma-ray burst with prompt emission detected by NuSTAR-ACS (CsI shields), Konus-Wind, and SVOM/GRM around 2026-05-19 13:45:36–38 UTC. The prompt light curve is described as multi-peaked with a total duration of roughly 25–27 s.
Wavelength coverage
- Gamma-rays / hard X-rays: Detected by SVOM/GRM (15–5000 keV) with event-by-event data and spectral/fluence/flux reporting.
- Gamma-rays: Detected by Konus-Wind with timing, fluence/peak flux, and Band/cutoff-PL spectral fits (20 keV–10 MeV).
- Hard X-rays (ACS/shields): Detected by NuSTAR CsI anti-coincidence shields; no evidence above 100 keV in NuSTAR CZT detectors is reported.
No observations are mentioned in optical/UV, infrared, radio, or TeV bands.
