General information
GRB 260402C is reported as a long-duration gamma-ray burst detected in prompt emission by AstroSat/CZTI, with corroborating prompt detection by NuSTAR SINGS.
Wavelength coverage
- Hard X-ray / gamma-ray: AstroSat/CZTI detection in 20–200 keV and Veto detection in 100–500 keV; NuSTAR CsI anti-coincidence shields detect prompt emission.
- X-ray: NuSTAR reports marginal evidence above 100 keV in the CZT detectors.
No observations are mentioned in optical/UV, IR, radio, or TeV.
