Nanni (INAF/OAR and Second University of Rome \"Tor Vergata\"),\nR. Gualandi (Bologna Observatory) report:\n\n\nWe observed the afterglow of GRB 071112C (Perri et al., GCN 7059) \nwith the 152 cm Cassini Telescope located in Loiano under clear \nsky conditions (seeing approximately  1.8 arcsec).\nWe  obtained three 20 min Rc-band images \nstarting on 2007 November 12.929 UT (mean time). \n\nIn our co-added images we estimated the following magnitude \nby comparison with the NOMAD1 catalog: Rc= 21 +/- 0.2\nThis result is consistent with a power-law index = -0.8 as\nreported by Burenin et al. (GCN7066) and Chen et al. (GCN 7083).\n\n\nThe co-added Rc image, in which the comparison stars are marked, has been\nposted in our public directory from where it can be retrieved\nby sftp using\nhostname: ermione.bo.astro.it\nusername: publicGRB\npassword: GRB_bo.\ndirectory: GRB071112C",
