Malesani (DTU Space), A. de Ugarte Postigo (HETH, IAA/CSIC), T. \nPursimo (NOT), report on behalf of a larger collaboration:\n\nWe observed the field of GRB 201015A (D'Elia et al., GCN 28632) using \nthe Nordic Optical Telescope (NOT) equipped with the ALFOSC camera. Our \nfirst image was taken at 23:25:12 UT (35 min after the trigger). At the \nlocation of the afterglow candidate reported by Lipunov et al. (GCN \n28633), also consistent with the XRT position (Kennea et al., GCN \n28635), we detect a source not visible in the Pan-STARRS images of the \nsame area. We report for this target the following, refined coordinates:\n\nRA(J2000) = 23:37:16.41\nDec(J2000) = +53:24:56.5\n\nwith an uncertainty of 0.3\" (calibrated against the Gaia catalog).\n\nOur image was taken with a non-standard, broad filter (~3700-9000 AA), \nand the target is affected by a saturation defect from a star. We cannot \nprovide a reliable magnitude at the present time, but a rough estimate \nyields ~19.",
