Abstract

We report on the analysis of three seasons of photoelectric photometry of 27 Cygni (KOIV) and

one season of radial velocities. The star shows marginal (but probably real) variability in both

light and velocity, on a time scale of weeks. further study of the star does not seem to be

warranted, but it should not be used as a comparison star for differential photometry of other

variable stars.
