Obs. of Rome), on behalf of a larger Italian collaboration, \nreport:\n\n\"A more accurate inspection of our R-band observation (Masetti et al., \nGCN #1811) of the HETE/SXC error box of GRB030115 (Kawai et al., \nGCN #1816) shows a faint object at the position of the variable K-band\nobject (Levan et al., GCN #1818). \n\nWe measure for this object a magnitude R ~ 21.5, assuming R = 16.7 for the\ncloseby USNO star U1050_06471524.\n\nA count excess at the position of this object appears to be present on the\nDSS2-Red also, suggesting that any R-band variability at the time of\nGRB030115 must be of low amplitude. The positional coincidence with the IR\ntransient however strengthens the reality of this object even if it is\nclose to the detection limit in both DSS2 and our R-band images. \n\nThis object might be the host galaxy if the IR source is indeed\nthe GRB afterglow. If this is true, the non-detection of a bright \nafterglow in the optical might be more likely due to a very high local\nextinction, rather than to the high redshift.\n\nThe optical counterpart to the radio source detected by Berger et al.\n(GCN #1817) is well detected on both the DSS2 and our R-band frame\nas an extended object with magnitude R ~ 20.\n\nThis message is citeable.\".",
