We present a CCD V light curve of HV 2241, together with some
observations in the B band.
We analysed our photometric data jointly with previously published radial
velocities by means of the Wilson-Devinney code, and derived new values
for the physical parameters of this massive eclipsing binary system.
We confirm that this system is semi-detached, with the secondary (less massive
and less luminous component) filling its Roche-lobe. From our analysis,
we estimate the following masses and radii for the components of HV 2241:
,
,
and
.
We review the spectral classification analysing HST and IUE data and discuss
the temperature and the reddening for this star.
