The combination of the first 32 images with an\nexposure mean time of 80s after the GRB has a limit of\n~17.6mag (calibrated against GSC2). Neither shows any new\nsources within the GRB errorbox.\n\nThe 1.5m telescope took a single I-band 300s exposure starting\nat 21:21:59 (mid exposure ~26.5 min after the GRB), this image\ndoes not reveal any new source in comparison with DSS-IR, but\ngoes deeper. Further comparison image would be needed to\nexploit full potential of this observation.\n\nThis message may be cited.",
