General information
GRB 260623A was detected as a likely long GRB by Fermi/GBM, with an additional gamma-ray detection by the Glowbug telescope on the ISS. An optical counterpart was reported as clearly detected by SVOM/VT with multi-epoch photometry.
Wavelength coverage
- Gamma-ray: Fermi/GBM trigger/localization; Glowbug detection with reported duration and significance.
- Optical: SVOM/VT detections in VT_B (400–650 nm) and VT_R (650–1000 nm) at ~1.28 h and ~3.19 h post-trigger.
No X-ray, UV, radio, IR, or GeV (LAT) observations are mentioned in these circulars.
