Complete uvby light curves of the detached triple-lined
late B-type eclipsing binary V906 Scorpii, secured from 1987
to 1991, are presented. A detailed photometric analysis based on
these observations and on new spectroscopic material yields
accurate masses and radii (errors 
2%) for the components, confirms
that the system is a member of NGC 6475 (Messier 7), and is published
separately (Alencar et al. 1997).
