C. Bartolini, A. Guarnieri, A. Piccioni (Dip. Astronomia, U. of Bologna), A. De Blasi (Oss. Astron. Bologna) and N. Masetti (ITeSRE-CNR, Bologna) report: "Five R-band images of the BeppoSAX WFC error box of GRB991217/SAX J2303.2+0015 (Muller et al. 1999, GCN #474) were obtained with the Bologna Astronomical Observatory 1.5-meter telescope equipped with BFOSC between Dec. 17.727 and 17.814, for a total exposure time of 55 min. These observations, which started about 13 hours after the high-energy event, were summed together and compared with the DSS-2. Altought somewhat deeper than the DSS-2, the summed R frame does not show any remarkable new object." This message can be cited.
