Abstract

A statistical analysis of the flare data on three UV Cet stars obtained at Catania Observatory in the indicated periods-UV Cet (1968–1976), EQ Peg (1969–1975) and YZ CMi (1968–1976)-is presented. The distributions of the four variables (i) ξ, the time elapsed from the start of a continuous observation interval to the occurrence of the first flare; (ii) η, the time interval between consecutive flares; (iii)k, the number of flares occurring in time intervals of given duration; (iv) δ, the ratio between the number of flares observed in each continuous observing interval to that expected for a Poisson process, indicate that the flares of the three stars considered are not randomly distributed in time.
