This paper presents new complete uvby light curves of the late-type detached eclipsing binary BH Vir (G0V + G5V, ). This binary system has been observed during four campaigns at the Calar Alto Observatory (Almeria, Spain) and at the European Southern Observatory (La Silla, Chile). This observations are part of a 6 year uvby and Hβ monitoring program of low mass eclipsing binaries which main objective is to provide accurate absolute astrophysical parameters for late-type main sequence stars. 1585 points spreaded over the binary period and covering both eclipses are given. The internal accuracy of the standard photometry measured as the mean RMS of the differences between standard value and observed value for the standard stars observed along the program is quoted in a few millimagnitudes. Detailed analysis of BH Vir, based on these light curves, will be published separately.
Key words: stars: binaries: eclipsing / stars: individual: BH Vir
Based on observations collected with the Danish 0.5 m telescope at the European Southern Observatory (ESO), La Silla, Chile and the Spanish 1.5 m telescope at Calar Alto, Almería, Spain.
