We obtained four R filtered images, with exposure \ntimes of 180 and 480 s.\n\nThe comparison between these images with the USNO-A2 catalog does not \nreveal any new source down to a limiting magnitude of R < 19.4 inside \nthe 80\" error circle around the position provided by the HETE SXC Ground \nanalysis (GCN 2588).\n\nThis message may be cited.",
