The addition of recent
observations to earlier data lead to the conclusion that a single parabolic O-C
curve may explain the past behavior of the RR Lyrae variable V783 Cygni, rather
than two separate line segments as previously suspected.These new parabolic elements, JD_max =
2436394.332 + 0.62069669 + 7.5 x 10^-11 E^2, imply a gradual period increase at
the rate of 0.088+-0.023 day/million years.
