General information
SVOM GRB 260119.92 triggered on 2026-01-19, with MASTER-Net reporting prompt follow-up observations and only optical upper limits. The MASTER reports quote an SVOM error radius of R=1 deg and provide early clear-band limits without an optical transient detection.
Wavelength coverage
- Gamma-ray / high-energy: SVOM trigger/localization is referenced in the follow-up reports (no prompt high-energy lightcurve/spectrum details given).
- Optical: MASTER-Tunka clear (C) band imaging with limiting magnitudes ~18.9–19.6 at ~7–14 minutes post-trigger.
No observations are mentioned in X-ray, UV, infrared, or radio bands.
Lightcurve and spectrum
- Optical limits: at Tmid-T0 ≈ 467 s, C-band limit 19.6 mag (also 19.3 mag in a second tile) (GCN 43462).
- Optical limits: at Tmid-T0 ≈ 869 s, C-band limit 19.4 mag (also 18.9 mag in a second tile) (GCN 43461).
