TITLE: GCN CIRCULAR NUMBER: 16172 SUBJECT: GRB 140413A: GROND Afterglow Confirmation DATE: 14/04/25 12:56:00 GMT FROM: Alexander Kann at TLS Tautenburg C. Delvaux (MPE Garching), D. A. Kann, S. Schmidl (both TLS Tautenburg), and J. Greiner (MPE Garching) report on behalf of the GROND team: We re-observed the field of GRB 140413A (Swift trigger 595616; D'Elia et al., GCN # 16098) simultaneously in g'r'i'z'JHK with GROND (Greiner et al. 2008, PASP 120, 405) mounted at the 2.2 m MPG telescope at La Silla Observatory (Chile). Further epochs were obtained at 1, 2, 3 and 5 days after the trigger. The source detected in the XRT error circle in early observations (Varela et al., GCN # 16099) has faded by about 3 magnitudes in the r' band, confirming that it is the afterglow of GRB 140413A. In the later epochs we obtain detections in g'r'i'z'J at a constant level, possibly the host galaxy of the GRB. If it is the host galaxy, this may be indicative of a relatively low redshift.
