Complete uvby light curves of the young detached double-lined massive O-type eclipsing binary V 3903 Sagittarii, obtained from 1989 to 1994, are presented. The observations were obtained at two different sites and a discussion of the characteristics of both data sets is included.
Key words: binaries: eclipsing: spectroscopic / stars: individual: V 3903 Sgr / stars: early-type
Based on observations done with the ZEISS 60 cm telescope at the Pico dos Dias Observatory (PDO), National Laboratory of Astrophysics, LNA–CNPq, Brasópolis, MG, Brazil, and with the Danish 50 cm Telescope (SAT) at the European Southern Observatory (ESO), La Silla, Chile.
