Pérez-Ramírez (Univ.\nde Jaén, Spain), S. Guziy (Nikolaev St. Univ., Ukraine) and\nA. J. Castro-Tirado (IAA-CSIC, Spain),\n\nreport:\n\n\"Following the detection by SWIFT of GRB 070616 (Starling\net al. GCNC 6542), we have obtained single VRI frames at the\n6m BTA SAO-RAS telescope at Nizhnij Arkhyz (Russia), starting\nat 23:57 UT (i.e. 7.5 hr after the event). Within the SWIFT/XRT\nerror box , we detect in all filters a faint (R ~ 22), reddened\npoint-like source. Preliminary astrometry yielded RA (J2000)\n= 02 08 36.00; Dec (J2000) = +56 56 41.0  (+/- 1\"), a position\nvery close to the USNO B-1 star reported by Kann et al. (GCNC\n6545). Further observations are needed to confirm if this is the\noptical afterglow to GRB 070616. \"\n\nThis message can be quoted.",
