Scientific paper

A total of 27 new times of minima of the eclipsing binary system CV Cyg
are added to the 39 found in the literature. These data show evidence
that the period of the system decreases by 1.175 + or - 0.078 x 10 to
the -9th day/cycle. This behavior appears to be due to rapid mass
exchange.
