Gualandi \n(Bologna Observatory) report:\n\nWe observed the field of GRB 080319B (GCN 7427, Racusin et al.)  \nwith the 152 cm telescope located in Loiano under unfavorable\nconditions due to the illumination of the full moon. \n\nBy adding four consecutive 10 min exposures in the Rc filter at \nmean time 2008 March 20.947 UT we do not detect any object at\nthe position of the optical bright afterglow reported by \nRacusin et al. (GCN 7428).\n\nOur 3-sigma limiting magnitude is R~20.3 (based on Nomad1 catalogue).\n\nThe image has been posted in our public directory \nfrom where it can be retrieved \nby sftp using \nhostname: ermione.bo.astro.it\nusername: publicGRB\npassword: GRB_bo.\ndirectory: GRB080319B",
