The white-light photometric observations from the Kepler mission are the first ever look at the behavior of solar-type stars at ultra-high precision, and the light curves made available in the "Q1” data release show many astrophysical phenomena. Especially evident in a small fraction of the G and K dwarfs are flaring events, with rapid rises and exponential decays. These flares have much greater energies and longer decay time-scales than even the largest solar flares, which would be undetectable given Kepler's 30-minute observing cadence. Moreover, stars that exhibit flares tend to show several flares during the 33.5 day interval covered by the Q1 data. Aside from the Kepler data itself, little is known about these stars and what sets them apart from other Kepler targets with similar rotation periods and variability amplitudes. We will show examples of flares in the Kepler light curves, describe our detection technique, and present our initial findings on this phenomenon.
