Levan report on behalf of a larger \ncollaboration:\n\nWe observed the field of GRB 090709A (Morris et al., GCN 9625) with the\nWilliam Herschel Telescope, using the LIRIS instrument.\nWe obtained a total of 1890 secs of exposure time in J band, under reasonable \nconditions, starting at 04:48 UT July 10th (20.8 hrs after burst).\n\nWe do not detect the afterglow (Aoki et al. GCN 9634; Morgan et\nal. GCN 9635), with limiting magnitude J>~20. Source A of Aoki et al is \nclearly detected.\n\nWe are grateful to Don Pollaco and Ian Skillen for performing these \nobservations.",
