7258 Pettarin           Discovered 1994 Mar. 5 at Santa Lucia Stroncone.
Enrico Pettarin (b. 1970), Italian amateur astronomer, has been for many years the "factotum" at the CCAF (Circolo Culturale Astronomico di Farra d´Isonzo) observatory in Farra d´Isonzo. He likes software, maintains the telescopes and has participated in almost all of the more than 200 new discoveries at this site.
