Query: V369 Gem: A New Ellipsoidal Variable System With High Level
  Chromospheric Activity   In this study, we present BVR photometry of V369 Gem in 2006 - 2008. We
combined our V data with the data taken from the literature. We analysed all
the data together and calculated the new light elements. General features of
the light curves were discussed. The light curves were modelled with the
Fourier method and the Fourier coefficients calculated. The cos(2theta) term
was found to be dominant. The pre-whitened V light curves demonstrated that
stellar spot activity also exist. There are generally two minima in the
pre-whitened light curves. Thus, there must be two spotted areas, which are
separated about 180 deg from each other. As conclusions, we have remarked for
the first time that V369 Gem is an ellipsoidal variable with the high level
chromospheric activity.
