After end of twilight, the observation was started at 12:42 (0.107 days after the burst). We have obtained 12 x 300 sec i'-band images. These images show no optical counterpart brighter than i'=17.2. These 3-sigma limiting magnitudes are derived from the USNO-B1.0 catalog. This message may be cited."
