Bruni (Osservatorio di Bologna) report:\n\nWe observed the error box of GRB050319 (SWIFT trigger 11162; Krimm et al.,\nGCN 3117) in Rc light on March 20 in good sky conditions (seeing approx.\n1.5 - 2 arcsec) but in presence of high contribution of moonlight with\nthe 152 cm G.D. Cassini telescope of Bologna University, equipped with the\nBFOSC CCD imager.\nWe got 4X1200s images with the following results: \nUT at start exposure        Exposure (s)       OT Rc mag        \n2005 March 20, 2:14           1200               19.58 (+- 0.18)\n2005 March 20, 2:37           1200               19.66 (+- 0.16)\n2005 March 20, 3:02           1200               19.67 (+- 0.16)\n 2005 March 20  3:25          1200               19.69 (+- 0.19)\nobtained using as comparisons the following objects extracted from\nthe USNO A2 catalog:\n                                     ID: 1275-07685084\n                                     ID: 1275-07684473\n                                     ID: 1275-07683651\n                                     ID: 1275-07685059\n                                     ID: 1275-07684793\n                                     ID: 1275-07685268\n                                     ID: 1275-07684751\n From our images, by comparison with the R magnitudes reported by CGN 3124,\n3139 and 3140 we infer a substantial rebrightening.
