Riffeser (Universitaets-Sternwarte Muenchen) \nreport:\n\n\"The error box of GRB 991208 (Hurley et al., GCN  450) was observed with the \nTautenburg Schmidt telescope on 1999 Dec. 11.21 UT in the I band. An object was \nfound whose position corresponds to that of the VLA radio source which is a \nstrong candidate for the afterglow from GRB 991208 (Frail et al. 1999, GCN 451).\nThis optical source is not visible in the Digitized Sky Survey. The detection of\nthe radio and optical sources which coincide in their positions within the\nastrometric errors strongly supports the view that their origin is the afterglow\nof the GRB. Photometric calibration of the I-band image is in progress. The\ncomparison of the brightness of the newly found object with nearby USNO stars\nindicates an I magnitude of about 19...19.5 mag. The presence of the optical\nsource is confirmed by independent observations of Castro-Tirado et al. (GCN\n452). The image can be found at \nhttp://www.tls-tautenburg.de/research/grb991208.html\"\n\nThis message is quotable.",
