The over 100 year data base of optical variations in OJ287 puts limits on these terms and thus tests the ability of Einstein's General Relativity to describe, for the first time, dynamic binary black hole spacetime in the strong field regime. The quadrupole-moment contributions to the equations of motion allows us to constrain the 'no-hair' parameter to be 1.0 +/- 0.3 which supports the black hole no-hair theorem within the achievable precision.
