We present results from our cycle 10 HST program to search for transition region emission in very low-mass main-sequence stars in the spectral range M7-M9. flaring and quiescent origin for the emission. We have obtained HST/STIS time series observations of three active very low mass stars (VB 8 VB 10 and LHS 2065) which show persistent activity in transition region lines including C IV Si IV and He II. The emission in these transition region lines is variable between exposures but is always observed. A strong flare was observed in one 10 minute exposure on VB 10. Our results indicate that active very low-mass stars maintain a persistent quiescent chromosphere and transition region that is similar to those observed in active earlier type M dwarfs in contrast to suggestions that these low-mass main-sequence stars exhibit only flaring activity.
