Eventually, six\nhours of observational data were obtained, with the last image taken at\n3:23:20 UT.\n\nWe clearly detect the afterglow reported by Ivanov et al. (GCN 11228),\nand at the the beginning of our sequence (coadded first 7x 20s, exp.\nmean time = 21:19 UT) we measure a magnitude 18.7 +- 0.2.\n\nThis message can be cited.",
