  After more than one year of operation, the Kepler photometer has already
provided exquisite data of solar-type stars. During the survey phase, 42 stars
have been continuously observed. It appeared that five stars show evidence of
oscillations, even though they are rather faint (magnitudes from 10.5 to 12).
We will show the results of the seismic analysis of the light curves of two of
these stars, which have been observed during more than 8 months. This analysis
led to the determination of the acoustic-mode global parameters (mean large
separation, mean small separation...), lists of frequencies built by comparing
the results of several teams, some parameters of the modes, and the rotation
period of the stellar surface.
