  The almost un-interrupted observations from Kepler Space Telescope can be
used to search for Earth-size and larger planets around other stars, as well as
for stellar variability and asteroseismological study. However, the Kepler's
observations are carried out with a single broad-band filter, and ground-based
follow-up observations are needed to complement Kepler's light curves to fully
characterize the properties of the target stars. Here we present ground-based
optical (BVRI) followup observations of V1154 Cyg, the only Cepheid in the
Kepler field of view, and deriving basic properties of this star.
