Palmerio, Ziqi Wang (GXU), Wenjin Xie (NAOC) \non behalf of the SVOM/VT team.\n\nAfter the trigger by SVOM/ECLAIRs (sb26111401) at 2026-11-14T09:33:13 UTC (T0), SVOM performed an automatic slew on the burst location (Li et al., GCN 46267). From a preliminary analysis of the 1-bit subimage and source list downloaded via VHF network, one credible candidate is identified, the details of which are presented below. The position of this candidate is R.A., Dec. 345.81339, -32.31699 degrees, corresponding to:\n\nR.A. (J2000) = 23h03m15.21s    \nDec. (J2000) = -32d19m01.2s    \n\nwith an uncertainty of 0.50 arcsec. This candidate was detected in both VT_R and VT_B band of the VT observations. The candidate's magnitudes are:\n\n| **date-obs (UTC)**      | **mid-time** - T0 | **exposure** | **VT_B mag(AB)** | **VT_R mag(AB)** |\n| ----------------------- | ---------------- | ------------ | ---------------- | ---------------- |\n| 2026-11-14T09:37:55     | 6.45 min         | 6*70 sec     | 19.54 +/- 0.02   | 18.09 +/- 0.01   |\n| 2026-11-14T09:46:05.000 | 14.55 min        | 6*70 sec     | 20.10 +/- 0.04   | 18.54 +/- 0.03   |\n\nMagnitudes were not corrected for Galactic reddening.\nThe Space-based multi-band astronomical Variable Objects Monitor (SVOM) is a China-France joint mission led by the Chinese National Space Administration (CNSA), French Space Agency (CNES), and the Chinese Academy of Sciences (CAS), which is dedicated to observing gamma-ray bursts and other transient phenomena in the energetic universe. SVOM/VT was jointly developed by Xi'an Institute of Optics and Precision Mechanics (XIOPM), CAS and National astronomical observatories (NAOC), CAS.\n\n",
