The images were calibrated\n    using the star quoted by Guidorzi et al.,  GCN 8989.\n    By summing 9 images in filter R, with a total duration of 2280s\n    obtained on March 14 between 00:41:11 and 01:27:59 UT, (mid exposure\n    time 15.97 hr after the burst) we find R mag = 19.26 +/- 0.15\n\n    Our  image has been posted in our public directory\n    from where it can be retrieved by sftp using\n    sftp publicGRB@137.204.66.221\n    password: GRB_bo\n    cd GRB090313",
