Author(s): Y. B. Goranova, K.P. Panov, M.S. Ivanova (Poster)

The well-known spotted flare stare EV Lac has been extensively observed at Rozhen National Astronomical Observatory (Bulgaria) since 1981. The presented data were collected in past 9 years (1992-2000) in the framework of the Stellar Activity program. During 36.317 hours of U-bandpass monitoring 14 flares were recorded. Flare parameters, as well as the cumulative distribution of the flare energies was obtained. A statistical analysis of this data sample was presented.
