Observed limits on evolution of the B0655+64 orbit provide new bounds on the existence of dipolar gravitational radiation, and hence on violation of the Strong Equivalence Principle.6 pages, 2 figures, to appear in proceedings: "Radio Pulsars," Chania, Crete, August 2002 (ASP conference series)AstrophysicsGeneral Relativity and Quantum Cosmologytext
