  The muon g-2 experiment at Brookhaven has been taking data since 1997.
Analyses of the data taken in 1997 and 1998, which include about 2% of the data
taken so far, have improved the experimental accuracy in the muon anomalous
magnetic moment to a(mu,expt) = 1 165 921(5) x 10**(-9) (4 ppm). The value
agrees with standard theory. Analysis of the 1999 data, about 25% of the
existing data set, is nearing completion and analysis of the 2000 data has
started. The experiment is preparing for another major data taking run, this
time storing negative instead of positive muon beams.
