Pizzichini (INAF/IASF Bologna) report:\n\nUsing the 152 cm Loiano telescope equipped with the\nBFOSC camera system, we obtained in poor sky conditions\n(seeing = 2.7 arcsecs) two Rc-band images (2 x 900 sec) of\nthe field of the GRB060403 (Boyd et al., GCN 4945, Mangano\net al., GCN 4947) starting at April 4.0778 and 4.0898\nrespectively. A preliminary comparison with the DSS-2 does\nnot reveal any new source brighter than the DSS-2 limit\nwithin 1' from the XRT location. Our co-added image reaches\na detection limit slightly deeper than Rc=19.\nThe Rc co-added image has been posted in our public\ndirectory from where it can be retrieved by sftp using:\nhostname: ermione.bo.astro.it\nusername: publicGRB\npassword: GRB_bo.",
