All pointed PSPC observations currently available from the ROSAT Public Data Archive with known T Tauri stars, Pleiads, or Hyads in the field are analyzed in order to study the evolution of coronal activity. 38 large flares can be attributed to late-type stars. A flare rate is derived for the different stellar samples making use of the flare duration and the observing time.
