General information
GRB 260429A is a likely short GRB triggered at 2026-04-29 23:24:02 UT, detected by Fermi/GBM and SVOM/GRM, with later IPN triangulation involving Konus-Wind and Mars Odyssey.
Wavelength coverage
- Gamma-ray: Fermi/GBM detection with duration/spectral fits and fluence/peak flux reported; SVOM/GRM detection with duration/spectral fit and fluence reported; IPN triangulation using Fermi/GBM + Konus-Wind + Mars Odyssey/HEND (+ SVOM/GRM).
- Optical: MASTER-OAFA observations starting ~24 ks after trigger, reporting only upper limits to ~17.9 mag (clear/C).
No X-ray, radio, IR, UV, or TeV observations were mentioned.
