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 17½ hours of far-UV (λλ1150-1950) 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 ~ 2 mag). The brightest UV flare spectrum (EQ Peg) is contrasted with that of the largest solar flare seen from ‘Skylab’.
