Accurate standard uvby indices are presented for 73 southern B, A, F and G stars in the V magnitude range 8.2 to 10.9. They cover all three transformation regions of the uvby system (Olsen 1983) well. Standard β indices are included for the 55 B, A, and F stars in the sample. Our results provide a useful set of secondary standards for CCD photometry with southern hemisphere 1-2 m class telescopes. A critical comparison with published photometry, in general based on fewer observations, is given.
