  This study sums up a major part of the red giant V449 Cygni measurements for
the years 1974 through 2022, obtained by visual and CCD GEOS observers, the
Unione Astrofili Italiani, and various automatized telescopes. It appears that
the light variations of V449 Cyg in the years 1970-1990 corresponded more to an
L-type star according to the GCVS classification, with irregular amplitude
variations, sometimes marked by a quasi-periodicity of about 100 days. Since
the mid-1990s, these variations have become more regular, with an amplitude of
about 0.7 magnitude in V, and a period of about 54,1 days, as shown by various
period search routines applied to the best recent CCD series. A longer period
of about 2000 days is possible to describe the long term variation of V449 Cyg.
Therefore, V449 Cyg appears to be an SRB-type star.
