Aims. We present near ultraviolet (NUV:1750 - 2800 °A) and far ultraviolet (FUV: 1350 - 1750 °A) light-curves for flares on 4 nearby dMe-type
stars (GJ 3685A, CR Dra, AF Psc and SDSS J084425.9+513830.5) observed with the GALEX satellite.
Methods. Taking advantage of the time-tagged events recorded with the GALEX photon counting detectors, we present high temporal
resolution (< 0.01 sec) analysis of these UV flare data.
