  The muon (g-2) experiment at BNL has completed four data runs for the
positive muon, beginning in 1997 and has just finished its first run for the
negative muon. Recently the analysis of a 1.3 ppm result based on the 1999 run
was completed and published (a_\mu^+ = 11,659,202(14)(6) x 10^-10). The result
shows a tantalizing discrepancy with the Standard Model prediction of 2.6 times
the combined experimental and theoretical uncertainty. The muon (g-2)
experiment at BNL is ultimately aimed at measuring the anomalous magnetic
moment of the muon with a relative uncertainty of 0.35 ppm.
