The Kepler mission is currently monitoring over 200,000 solar-like stars across a 105 square degree FOV in the Cygnus-Lyra region. Its main purpose is to find Earth-size and smaller planets via transit observation, but many of the Kepler targets are likely not host stars of planetary candidates. A significant number of these non-transit targets display variability - periodic and otherwise - that can be characterized more precisely than ever before due to Kepler's continuous and high-precision photometry. Here we present the analysis of a sample of Kepler targets using a weighted wavelet Z-transform as described in Foster (1996) to recover trends in variability. Our results not only support the calibration of all Kepler data and show its superior quality, but demonstrate the possibility of Kepler to transform and expand current understanding of variable stars.
