BABAR has collected 5 fb^-1 of data at the °(4S) resonance and is well on the way to its target of 12 fb^-1 by the shutdown at the end of August. A preliminary analysis of the D* l n and D* p channels has given a measurement of the B⁰ and D⁰ lifetimes and enabled the mis-tag fraction in BSUP>0-antiB⁰ decays to be measured. A good understanding of the detector has enabled a study of inclusive J/y and K_s production, and the reconstruction of the exclusive channels J/y K_s and J/y K^±. Emphasis will be placed in the talk on using the data to measure CP violation.
