Narrow-band CCD images of the HH 46/47 system were obtained in the light of the H-alpha, forbidden N II 6583-A forbidden S II 6717-A and forbidden S II 6731-A emission lines. The images include HH 46, HH 47B, and HH 47A. A calibration for these images was carried out that makes it possible to calculate line ratios, and then use these line ratios as diagnostics of the physical conditions in the radiating gas. The study shows that the bright condensation HH 47A has a higher electron density and a lower excitation spectrum than the jet that joins this condensation to the central source. This result does not agree with the observations of other morphologically similar Herbig-Haro objects. 36 references.
