Abstract: The muon g-2 collaboration has measured the anomalous magnetic g value of the positive muon to within a relative uncertainty of 0.7 parts per million. The result, a_{μ^+} = 11 659 204(7)(5) x 10^{-10} is in good agreement with the preceding data on a_{μ^+} and a_{μ^-} and has about twice smaller uncertainty. The measurement tests standard model theory, which at the level of the experimental uncertainty involves quantum electrodynamics, quantum chromodynamics, and electroweak interaction in significant ways. The analysis of the anomalous magnetic g value of the negative muon is well underway.
