Abstract
We present 30 new nearby (d <30 pc) red dwarf candidates, with estimated sp ectral types M 6 to M 8. 26 were directly selected from the DENIS database, and another 4 were first extracted from the LHS catalogue and cross-identi fied with a DENIS counterpart. Their proper motions were measured on the MA MA measuring machine from plates spanning 13 to 48 years, and are larger th an 0.1 yr(-1), ruling out the possibility that they are giants. Their dista nces were estimated from the DENIS colours and IR colour-magnitude relation s and range between 15 and 30 pc.
