A comprehensive as of November 2003 and evaluated data compilation on sigmatot(e+ e- --> hadrons) was used to estimate the lowest order hadronic contribution to the muon anomalous magnetic moment. The preliminary result is amu(had, LO) = (699.6 +- 1.9(rad) +- 2.0(proc) +- 8.5(e+e-)) * 10-10 The Standard Model value of the muon magnetic anomaly calculated by updated SM formulae published or e-printed by November 2003 then reads amu = (1 165 918 3.5 +- 8.7(had) +- 4.0(LbL) +- 0.3(QED) +- 0.2(EW)) * 10-10. This result deviates from the current experimental world average of amu by (-19.5 +- 9.6(theor) +- 8.0(exp)) * 10-10, i.e. at 1.5 sigma level.
