TITLE: GCN CIRCULAR NUMBER: 5672 SUBJECT: GRB 060807: Detection of a possible host galaxy DATE: 06/10/01 17:32:47 GMT FROM: Christina Thoene at Niels Bohr Institute,DARK Cosmo Ctr Christina C. Thoene (DARK Cosmology Centre), Christina Henriksen (DARK, NOT) and Klaas Wiersema (Univ. of Amsterdam) report: We observed the field of GRB060807 on Sep. 20 and 22 with ALFOSC at the NOT on La Palma in V, R and i. At the position of the afterglow (GCN 5420), we detect an extended source, clearly visible in stacked images from all three filters (8x600s in V and R, 9x600s in I). We therefore conclude that the source is very likely the host galaxy of GRB060807. Photometry of the source gives values of V=24.9 +-0.1, R=24.26 +-0.05 and i=22.1 +-0.2 using photometric zeropoints from the NOT/ALFOSC webpage. This is a very red color as it was found for the color of the OT (GCN 5422) and might indicate a high redshift for this GRB. More bands however are required for a final conclusion. An image of the host in the R-band can be found at www.astro.ku.dk/~cthoene/GRBs/
