TITLE: GCN CIRCULAR NUMBER: 14782 SUBJECT: GRB 130606A: optical afterglow with BOOTES-2/TELMA and 1.23m CAHA DATE: 13/06/06 22:10:41 GMT FROM: Alberto Castro-Tirado at Inst.de Astro. de Andalucia M. Jelinek (IAA-CSIC), J. Gorosabel (UPV-EY, IAA-CSIC), A. J. Castro-Tirado (IAA-CSIC), S. Mottola (DLR), S. Hellmich (DLR), R. Fernández-Muñoz (EELM-CSIC) and V. F. Muñoz-Martínez (UMA), on behalf of a larger collaboration, report: "Following the detection of GRB 130606 by Swift (Ukwatta et al. GCNC 14781), follow-up observation were taken with the 0.6m TELMA telescope at the BOOTES-2 station (Málaga) and with the 1.23m CAHA telescope at the German-Spanish Calar Alto Observatory, starting 21m postburst. At the edge of the Swift/XRT error box we identify an optical source not present in the DSS-2 with a magnitude of R about 18.5 which we identify as the optical afterglow."
