TITLE: GCN GRB OBSERVATION REPORT NUMBER: 1353 SUBJECT: GRB 020409, optical observations DATE: 02/04/11 05:49:19 GMT FROM: Sylvio Klose at TLS Tautenburg B. Stecklum, S. Klose, A. Zeh (Thueringer Landessternwarte Tautenburg), D. H. Hartmann, M. Leising (Clemson University), A. A. Henden, F. J. Vrba (USNO/USRA, Flagstaff), J. Greiner (AIP Potsdam/MPE Garching) report: The error circle of GRB 020409 (Piro et al., GCN #1347) was imaged in the I band on April 10/11 with the Tautenburg Schmidt telescope equipped with the prime focus CCD camera (2k x 2k; fov about 35 x 35 arcmin), covering the full BeppoSAX error region. Altogether 6 images were taken, 10 min exposure time each. The combined image goes considerably deeper than the DSS2 infrared survey. We detect no obvious new point source brighter than I = (20 +/- 0.5) mag within the GRB error circle. Further observations are planned. This message can be quoted.
