The elevation of the field\ndecreased from 31 degrees above horizon and weather conditions\nwere good.\n\nThe first image is trailed with a duration of 60.0s\n(see the description in Klotz et al., 2006, A&A 451, L39).\nWe recorded the rise of the afterglow discovered by\nMelandri et al. (GCNC 14843).\n\nWe used the star NOMAD1 1182-0257977 R.A.=224.3892908\nDEC=+28.2065917 R=14.11 to extract the light curve\nof the rise of the afterglow:\n\nstart end     Rmag\n(sec) (sec)\n   91   97   > 17.8\n   97  103   > 17.8\n  103  109   > 17.8\n  109  115   > 17.8\n  115  121   > 17.8\n  121  127     17.7\n  127  133     16.9\n  133  139     16.5\n  139  145     16.6\n  145  151     16.1\n\nMagnitudes are not corrected for galactic dust extinction.\n\nAfter the trailed image a technical problem prevented\nto obtain next images.",
