WebAbstract. The UV Cet-type star flares and the chromospheric flares of the Sun have many important common features. Both types of events are very transient; they occupy only small parts of the stellar surfaces; in both cases the optical as well as the r)adio emission s of the flares have strong similarities in temporal and spectral characteristics.
