Abstract (from CDS):

The flares fine structure lies often below the detection limit for photometry data. UBVRI high-speed observations combined with synchronous monitoring at two telescopes situated far from each other allowed us to detect new small-amplitude features in the flare activity of EV Lac. Digital filtering of the light curves with a Gaussian window was used. We found that some flare events are composed of a flare and an intensity drop having a crater-shaped structure centered at the flare peak. Fading amplitudes extend from 0.1 to 0.01mag.
