We present the results of a 6 month monitoring campaign of Mkn 876, a
low luminosity quasar with M(abs) approximate to -24. High resolution
spectroscopy and direct imaging in the Johnson filters B, V, R, I was
carried out in the first half of 1990. Line and continuum light curves
are presented. Mkn 876 showed a decrease of 17% in the continuum over
the whole observing period whereas the line flux of H beta and H alph
a stayed constant. This implies, that the radius of the Broad Line Reg
ion is larger than 6 light months. Coadded spectra of H beta and H alp
ha are presented which confirm an extreme asymmetry of the line profil
es to the red. With respect to much earlier spectra the line profiles
changed considerably.
