  PHOTOELECTRIC MINIMA AND NEW ELEMENTS FOR V477 CYG


From 1963 to 1967 we obtained at the Nurnberg Observatory 5 photoelectric
minima of the eclipsing variable V477 Cyg, which show large, increasing O-C's
against the elements in GCVS (I) and SAC 38 (II). The period, given in GCVS
(1958) and SAC 38 (1967), was derived by Wallenquist immediately after the
discovery of the variability of V477 Cyg in 1957. The new elements (III),
calculated from the Nurnberg observations with the method of least squares,
give a considerable shorter period.
