Four low activity dM(e) stars Gl 105B, Gl 643, Gl 813 and Gl 821 were observed spectroscopically in the optical and ultraviolet regions. Despite relatively long integrations, only one of the four had detectable {\it Ca II K\ } emission, Gl 821, which had an observed flux of 9 10$^{-15}$ {\it erg cm}$^{-2}$ {\it s}$^{-1}$, giving a surface flux of only 0.8 10$^{4}$ {\it erg cm}$^{-2}$ {\it s}$^{-1}$. ...
