Castro-Tirado (IAA-CSIC), on behalf of a larger collaboration, report;
We have carried out I-band observations of the XRT position of GRB
090813 (GCN 9781) with the 1.23m telescope of Calar Alto. The
observations started at 04:18 UT (437 s after the GRB trigger). We
detect an object with a rough magnitude of I~17 coincident with the XRT
position no present on the DSS. We propose that object as the optical
afterglow of GRB 090813.
