The SVOM mission team observed the field of GRB 260914A using the LCO 1m telescope at Siding Spring Observatory, detecting the optical counterpart in the r-band with a magnitude of 20.9 AB. The observation was conducted approximately 3.81 hours after the initial detection, and the measured magnitude is contaminated by an underlying object and a nearby galaxy.

The SVOM satellite detected a gamma-ray burst, GRB 260914A, on September 14, 2026, and identified an optical afterglow at coordinates R.A. 2h06m23.8s and Dec. 29d15m17.5s. The afterglow was observed to fade over time, confirming its transient nature.

GCN-45564 — GRB 260914A · Mon, 14 Sep 2026 13:58:55 GMT
A possible optical counterpart to the gamma-ray burst GRB 260914A was detected by the SVOM/COLIBRÍ (FM-GFT) telescope, with preliminary magnitudes of 20.14 ± 0.04 in the r-band and 19.66 ± 0.04 in the z-band. Additional observations are encouraged to confirm the nature of the source.

GCN-45562 — GRB 260914A · Mon, 14 Sep 2026 11:50:35 GMT
The SVOM mission detected a gamma-ray burst, GRB 260914A, on September 14, 2026, at 11:12:31 UTC. The burst was localized to RA 2h06m10.06s, Dec 29d15m41.72s with a 90% confidence level radius of 6.33 arcmin, and had a T90 duration of approximately 4.33 seconds, indicating a significant transient event in the energetic universe.
