ISS and Progress chasing each other

This evening I finally was able to see the ISS and the recently decoupled Progress M-02 M (09-024A) cargoship chasing each other over the sky. The couple was some 20 degrees apart, with the Progress leading. A very neat sight.

The Progress was around +2.5 to +3, ISS attained about -3.5 and was distinctly orange. The photo below shows the couple while still low in the sky, ascending in the west.

I also observed USA 161 (01-044A) passing east some 10 minutes later.
