GCN 450) with the 2.5-m Isaac Newton\ntelescope at La Palma and with the 2.2-m telescope at the German-\nSpanish Calar Alto Observatory.  The images were taken on Dec 10.27\n(I-band) and Dec 11.25 UT (R- and I-band filters).\nAfter a visual comparison with the Digital Sky Survey, a new source\nis clearly detected with R = 19.1 +/- 0.1 (Dec 11.27). Its position\nis AR(2000) = 16h 33m 53.51s, Dec(2000) = +46 27 21.5 (+/- 1\"). We note\nthat this object coincides with the radio source reported by Frail et al.\n(GCN 451) and therefore is the optical afterglow to GRB 991208. Further\nmultiwavelength imaging and spectroscopy are encouraged. A finding\nchart will be posted at http://www.laeff.esa.es/~ajct/GRBs/GRB991208\"\n\nThis message is quotable.",
