A CCD V light curve for the eclipsing binary star AzV 73 is
presented. This new photometric observations are analysed together with
previously published CCD I photometry from Udalski et al. ([CITE])
and spectrographic data from
Niemela & Bassino ([CITE]), by means of the Wilson-Devinney code. It is
found that this system is semi-detached, with an orbital inclination of
roughly 
and a separation of 
.
The sizes and masses are 
, 
, and 
,
for the primary and secondary components, respectively.
Key words: binaries: eclipsing / stars: early-type / stars: fundamental parameters / stars: individual: AzV 73
