Wei (NAOC), K. Liu (GXU), Y.N. Ma (NAOC) report on behalf of the SVOM/C-GFT team:\n \n \nWe observed the field of GRB 260914A detected by SVOM/ECLAIRs (Wang et al., GCN 45562) with LATIOS on SVOM/C-GFT. Observations started at 2026-09-14T12:11:29 UTC, ~0.98 hr after the trigger. \n\nThe optical candidate (Akl et al., GCN 45564; Palmerio et al., GCN 45565; Li et al., GCN 45566) was faintly detected in our stacked images of band  i.  The magnitude is:\n|[date-obs(mid-time)] | Mid_t-T0(h) | exposure time (s) | band | mag (AB) | mag_err|\n|--------------------|--------------|-------------------|------|----------|--------|\n|2026-09-14T13:06:45 |  1.9         | 30×90s           | i    | 20.15   | +/- 0.12  |\n\nThe photometry was calibrated against Pan-STARRS1 DR1 catalogue and no correction for Galactic dust extinction was applied.\n\nWe thank the observation assistants H.-X. Xue and B.-W. Li at Jilin observatory for their excellent support.\n\nThe Chinese Ground Follow-up Telescope (C-GFT) for the SVOM mission is located at Jilin Station, Changchun Observatory, National Astronomical Observatories, CAS. It features two instruments: (1) CATCH at the Cassegrain focus with a 21 arcmin x 21 arcmin FOV for simultaneous g/r/i-band imaging, and (2) LATIOS, a 4k x 4k CMOS camera at the prime focus with a 1.28 deg x 1.28 deg FOV that images in g, r, and i bands via filter switching.\n",
