The 3-sigma limiting magnitude\nof the image, estimated using USNO-A1.0 field stars, is R~23.5.\nComparison of our image with the DSS did not reveal any new object\nbrighter than the DSS limit (R~21) 7.7 hours after the GRB trigger. \nThe FITS file of the R frame as well as a .gif image can be found at the\nURL http://www.sao.ru/~zhar/home/GRB/991106.html .\".\n\n\nThis message can be cited.",
