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.
