Gnaoui (IAP) report on behalf of the SVOM mission team:\n\n\nWe observed the field of GRB 261108C (SVOM burst-id sb26110812) detected by SVOM (Hamburg et al., GCN 46198) with the LCO 1m telescope at South African Astronomical Observatory equipped with the Sinistro instrument.\n\nOur observation started on 2026-11-08T21:23:19 UT (about 4.15 min after the trigger) and we obtained 3x200 s exposures in the SDSS r and Pan-STARRS z filter.\n\nIn the stacked image, we do not detect any new source within the SVOM/ECLAIRs error box. We measure the following upper limits calibrated against the DESI Legacy Imaging Surveys DR10 catalog, and not corrected for Galactic extinction:\n\nr > 22.1 AB (5-sigma, mid-time 27.10 min after the trigger),\nz > 19.9 AB (5-sigma, mid-time 9.58 min after the trigger).\n\nThis project is funded by the SVOM collaboration.",
