Description

Four large flare events - one on each of the dMe stars UV Cet, AT Mic, EV Lac and EQ Peg - have been witnessed during a total of 17 1/2 hours of far-UV (lambdalambda1150-1950) IUE exposures. Some observational characteristics of these four events are compared. Two showed strong enhancements of chromospheric and transition-region line strengths. The other two did not, even though their visible flares were intense (ΔU approx. 2 mag.). The brightest UV flare spectrum (EQ Peg) is contrasted with that of the largest solar flare seen from 'Skylab'. (Auth.)
