This paper analyzes the
behavior of the RR Lyrae type variable star XZ Cygni over the past nine years.
One hundred visual light curves were analyzed, and forty selected, from wich
primary and secondary (Blazhko) periods were computed. Findings indicate that
the primary period of XZ Cygni has remained almost equal to that derived by
Baldwin (1973), or 0?466474, at least through 1974. The secondary period was
calculated to be 58?318, through 1973. This result, although considered only an
average, also approximates Baldwin's determination. In addition, times of
maxima reveal a relationship of O-C residuals and maximum magnitude with
secondary phase position.
