Wang (NAOC), report on behalf of the SVOM follow-up team:\n \nWe observed the field of GRB261007A detected by SVOM/ (Goto et al., GCN 45824), with the GWAC-F60 at Xinglong Observatory, China. F60 started observing at 2026-10-07T14:00:22.98 UTC in R-band.\n\nThe optical counterpart (Zheng et al., GCN 45825; Saccardi et al., GCN 45829; Mohan et al., GCN 45832; Saccardi et al., GCN 45837; Shi et al., GCN 45838) is faintly detected in our images. We measure the following magnitudes calibrated against the USNO-B1.0 catalog, and not corrected for Galactic extinction: from forced photometry of the faint source,\nR = 20.15 +/- 0.3 mag (mid-time 8.8 hr after the trigger);\n\nTwo 60cm GWAC-F60(A/B) are operated by Guangxi University and NAOC, CAS, at Xinglong Observatory, China. The field of view is 19*19 arcmin.\n",
