We propose to use the archival database from the SWEEPS project {Sahu et al. 2006a} to quantify the incidence of stellar flaring among Galactic dwarfs. The long time series {continuous 7 days viewing} coupled with short individual exposures { 5 minutes in V and I} occupies a unique niche in the parameter space of optical transient studies. Time-series data are available for 230,000 stars down to V=29.5 {mass of 0.25 Msun}; the resultant mass function shows that there are more than 100,000 M stars which can be used to look for flares. Due to their dependence on the presence and dynamics of interacting magnetic fields, stellar flares are a diagnostic of transient magnetic activity, in addition to more commonly used persistent indicators, and thus provide a complementary diagnostic of the presence and action of large-scale magnetic fields. Recent results from deep optical fast transient searches indicate the prevalence of stellar flaring and bolster support for a better quantification of the stellar flare rate. The stellar flare rate is also an important input to astrobiological studies on the effects of stellar flares on exoplanets in M dwarf planet-hosting systems. We will use this data to determine the stellar flare rate as a function of mass, temperature, and apparent magnitude in stars of intermediate-old age and compare to the decline of magnetic activity seen in younger stellar populations.;
