New broadband UBVRI photoelectric observations on the Johnson-Kron-Cousinsphotometric system have been made of 202 stars around the sky, and centered atthe celestial equator. These stars constitute both an update of and additionsto a previously published list of equatorial photometric standard stars. Thelist is capable of providing, for both celestial hemispheres, an internallyconsistent homogeneous broadband standard photometric system around the sky.When these new measurements are included with those previously published byLandolt (1992), the entire list of standard stars in this paper encompasses themagnitude range 8.90 < V < 16.30, and the color index range -0.35 < (B - V) <+2.30.
