Adrien (CEA/Irfu), report on behalf of the SVOM mission team:\n\nWe observed the field of GRB 260211A (Gotz et al., GCN 43705) with the LCO 1-m telescope at Cerro Tololo Interamerican Observatory equipped with the Sinistro instrument.\n\nOur observation started on 2026-02-12 at 02:37:50 UT (about 7.22 hr after the trigger) and we obtained 3x200 s exposures in the SDSS r filter. In the stacked image, we do not detect any new source within the SVOM/ECLAIRs error box, in agreement with Globus et al. (GCN 43707).\n\nWe measure the following upper limit calibrated against the UCAC4 catalog, and not corrected for Galactic extinction:\n\nr > 22.2 AB (5-sigma, mid-time 7.28 hr after the trigger).\n\nThis project is funded by the SVOM collaboration.",
