WebA couple of flare stars show more than one flare during the ROSAT obser vation. A particular example is the Hyades member Hz 2411, a well-known dMe flare star, for which Gurzadyan (1980) finds a mean frequency of optical flares of 1 every 11 hours. In the 20 hour patrol time of the ROSAT observation there are two large X-ray flares (Fig. 1).
