Jelínek (IAA-CSIC),\n\nreport:\n\n\"Following the detection of GRB 050713 by Swift\n(Falcone et al. GCNC 3581), we obtained R-band\nimages at the 2.5m Nordic Optical Telescope\n(+ ALFOSC) starting on June 13.295 UT (about\n47 min after the burst onset). We confirm the\npresence of an optical source fainter than the DSS-2\nlimiting magnitude within the reported Swift/XRT\nerror box, at RA(2000) = 21 22 09.53,  Dec(2000) =\n+77 04 29.5 (+/- 0.4\"), consistent with the position\nreported by Malesani et al. (GCNC 3582). Further\nobservations are needed in order to confirm if this\nis the optical afterglow to GRB 050713. \"\n\nThis message can be cited.",
