Abstract (from CDS):

Photoelectric, photographic and CCD UBV photometry, spectroscopic observations and star counts are presented for the open cluster Berkeley 58 to examine a possible association with the 4.37d Cepheid CG Cas. The cluster is difficult to separate from the early-type stars belonging to the Perseus spiral arm, in which it is located, but has reasonably well-defined parameters: an evolutionary age of ∼108yr, a mean reddening of E(B - V) (B0) = 0.70±0.03 s.e. and a distance of 3.03±0.17kpc (V0-MV= 12.40±0.12 s.d.). CG Cas is a likely cluster coronal member on the basis of radial velocity, and its period increase of +0.170±0.014 s/yr and large light amplitude describe a Cepheid in the third crossing of the instability strip lying slightly blueward of strip centre. Its inferred reddening and luminosity are E(B - V) = 0.64±0.02 s.e. and <MV> = -3.06±0.12. A possible K supergiant may also be a cluster member.
