Mateo Sanguino (Univ.\nHuelva, Spain)\n\nenunciate sadly\n\nthat the optical candidate reported by ourselves in previous\nGCN (Jelinek et al., GCN3498) is in fact a star, which is not\npresent in GSC2 catalogue. This mislead me (MJ) and although\ndoing a double-check using DSS, I have missed the star, thus\nconvincing myself about reality of the object.\n\nWe apologize to the comunity for a false alert.\n\nAnyhow: The BOOTES-1B has observed the errorbox starting 71s\nafter the trigger in a light twilight, setting the limit to\nthe possible GRB counterpart to V>13.8 and I>13.0 during the\nfirst 60s after the beginning of our observation.",
