Since June 2003, the NASA GALEX mission has been surveying the sky at
ultraviolet wavelengths from 1350-2800  Angstroms, observing much of
the sky away from the galactic plane (abs(b)>20  degrees).  In the
course of its surveys, GALEX has serendipitously detected hundreds of
energetic flares on M-dwarf stars, with an unprecedented
time-resolution of <0.01s.  These high time-resolution photometric
data in two bands (FUV and NUV) can be used to place constraints on
flare models and determine flare frequency.  GALEX has also obtained a
single grism spectrum of a flare event on the M-type dwarf 2MASS
03324199-2757029.
