We present long-slit optical spectroscopy of the HH7-11 complex at low (lambda / Delta lambda ~ 500) and moderate (lambda / Delta lambda ~ 2500) resolutions, as well as narrow-band images in Hα , [S II], [C I] lambda9849 , and continuum filters. We use these spectra to calculate the densities and temperatures as a function of position along the train of HH knots, and apply simple statistical equilibrium models in an effort to explain the anomalously high [C I]/Hα ratios ( ~ 3.3) observed in this object. In addition we compare our spectroscopic results with the narrow-band images in order to study the spatial variation of the [C I] emission across the complex.
