Belkin (IKI, HSE) on behalf of GRB IKI\nFuN report:\n\nWe observed the TRT candidate afterglow position (An et al., GCN 36815) of\nthe X-ray transient EP240703a (Wang et al., GCN 36807) and probable\ngamma-ray burst GRB 240703A (Frederiks et al., GCN 36809) with BTA SAO RAS\ntelescope equipped with SCORPIO-1 camera in Ic filter starting on\n2024-07-03 (UT) 20:50:07, i.e. 0.856 days after burst.\nWe did not detect the TRT candidate afterglow (An et al., GCN 36815) which\nmight be a spurious event (An et al., GCN 36820). At the stacked images of\n9x180 s we obtained an upper limit of Ic= 24.6m (3 sigma). We cannot\nconfirm that the TRT afterglow candidate (An et al., GCN 36815) is real.\nOur result is consistent with reported results (Aryan et al., GCN 36819,\nBochenek and Perley GCN 36821; Fernandez-Garcia et al., GCN 36822).\n\nWe are grateful to the Directorate of the Special Astrophysical Observatory\nfor allocation of  the TOO observation.\n",
