Abstract:	We present an updated measurement of time-dependent CP-violating asymmetries in neutral B decays with the BABAR detector at the PEP-II asymmetric B Factory at SLAC. This result uses an additional sample of T(4S) decays collected in 2001, bringing the data available to 32 million BB pairs. We select events in which one neutral B meson is fully reconstructed in a final state containing charmonium and the flavor of the other neutral B meson is determined from its decay products. The amplitude of the CP-violating asymmetry, which in the Standard Model is proportional to sin2β, is derived from the decay time distributions in such events. The result sin2β = 0.59±0.14 (stat)±0.05 (syst) establishes CP violation in the B0 meson system. We also determine \|λ\| = 0.93±0.09 (stat)± 0.03 (syst), consistent with no direct CP violation.
