Liu (GZNU) report on behalf of the SVOM mission team:\n\nWe observed the field of GRB 260705A (SVOM burst-id sb26070502) detected by SVOM (Saccardi et al., GCN 45079) with the LCO 1m telescope at South African Astronomical Observatory equipped with the Sinistro instrument.\n\nOur observation started on 2026-07-06 at 03:52:16 UT (about 14.76 hr after the trigger) and we obtained 3x200 s exposures in the SDSS r and 3x200 s exposures in the Pan-STARRS z filters.\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 > 20.9 AB (5-sigma, mid-time 14.85 h after the trigger);\nz > 19.9 AB (5-sigma, mid-time 15.06 h after the trigger).\n\nThis project is funded by the SVOM collaboration.",
