Abstract.

HST data on Cepheid variables in one Virgo Cluster spiral galaxy is re-analyzed, taking into account flux-limited incompleteness in the sample and calibration of the period-luminosity relation in the relevant period range. Distance to the Virgo Cluster is estimated to be 19.6 ±1.7 (random) ±2.6 (systematic) Mpc.

Keywords Cepheids; distance scale; hubble constant.
