Scientific paper

We present flare rates and analysis of individual flares using time-resolved spectra of M dwarfs from the Sloan Digital Sky Survey Data Release 5. Each of the 40,000 M dwarf spectra from the West et al. (2008) DR5 sample represents a co-addition of several shorter (9-15 min) spectra. We analyze nearly 200,000 of these short spectra, subdividing them by spectral type and by signal-to-noise ratio and use statistical methods to assign variability and flaring status. These data allow us to investigate the spectroscopic time-domain properties of low-mass stars.
