TITLE: GCN CIRCULAR NUMBER: 6912 SUBJECT: GRB 071013: optical observations at NOT DATE: 07/10/13 23:30:48 GMT FROM: Daniele Malesani at Niels Bohr Inst,Dark Cosmology Center D. Malesani, (DARK), J. Gorosabel (IAA-CSIC), P. Jakobsson (Univ. Hertfordshire), J.P.U. Fynbo (DARK), J. Niemela, C. Villforth (NOT) report on behalf of larger collaboration: We observed the field of GRB 071013 (Marshall et al., GCN 6907) using the Nordic Optical Telescope. Observations were carried out in the R and I filters, with mean integration epochs on Oct 13.867 and 13.894 UT (8.65 and 9.30 hr after the GRB). By comparison with the DSS, we do not detect any obvious candidate afterglow down to the DSS limiting magnitude R~20.5. Further observations are planned. [GCN OPS NOTE(14oct07): Per author's request, the Fynbo affiliation was changed from "NOT" to "DARK".]
