D'Avanzo\nand N. Masetti, performed at TNG telescope.\nIn the second image, less deep, the object is hardly visible.\n\nThe first image of the OT is posted into a public directory from where\nit can be retrieved by sftp using\nhostname: ermione.bo.astro.it\nusername: publicGRB\npassword: GRB_bo\ndirectory: GRB050401\".",
