This paper presents new complete uvby light curves of the late-type detached eclipsing binary BH Vir (G0V + G5V, P =0 : 81687099). This binary system has been observed during four cam- paigns at the Calar Alto Observatory (Almeria, Spain) and at the European Southern Observatory (La Silla, Chile). This observations are part of a 6 yearuvby and H monitoring program of low mass eclipsing binaries which main objective is to provide accurate absolute astrophys- ical 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 dierences between standard value and observed value for the stan- dard 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.
