TITLE: GCN CIRCULAR NUMBER: 12230 SUBJECT: GRB 110801A: TLS Optical afterglow confirmation DATE: 11/08/01 21:22:52 GMT FROM: Ana Nicuesa at TLS Tautenburg GRB 110801A: TLS Optical afterglow Confirmation A. Nicuesa Guelbenzu, X. Luo, S. Klose, U. Laux, B. Stecklum (all at TLS Tautenburg) report: We observed the afterglow of GRB 110801A (M. De Pasquale et al., GCN 12228) with the 2m/1.34m Schmidt telescope of the Thueringer Landessternwarte Tautenburg starting about 20 min after the GRB trigger. The afterglow is clearly detected in the R band images at the position of the UVOT detection. We confirm the re-brightening of the afterglow as reported by ROTSE III (Zheng et al. 2011, GCN 12229).
