Liu (XAO) report:\n\nWe observed the field of GRB 260515A (sb26051504; Brunet et al., GCN 44622) using the JinShan 100B telescope located at Altay, Xinjiang, China. We obtained a series of frames in the Sloan i-band.\n\nAn uncatalogued and varying source is detected within the SVOM/ECLAIRs error circle at coordinates\nR.A. (J2000) = 227.6852 deg\nDec. (J2000) = 24.5562 deg\nwith an uncertainty of ~ 1.0 arcsec. The source had i ~ 16.5 mag at a median time of ~ 11 min post-trigger, calibrated with Pan-STARRS1 DR2 and not corrected for Galactic extinction.\n\nWe acknowledge the excellent support from T.Q. Chen, and J.F. Zhang for enabling these observations.",
