I believe that Superbird A was a Japanese communications satellite that had a attitude propellant leak in Dec 90. It is in supersynchronous orbit and at times flashes to about magnitude 3 (naked eye). We are trying to determine when it will flash again in the US. This involves an understanding of the satellite configuration and spin characteristics. People like Rob Matson have the smarts to analyze that. I just observe.
