Scientific paper

Deep near-infrared images and long-slit spectra of the HH 111 jet region are presented. Two bipolar jets were detected; the HH 111 jet, and a new optically invisible jet, HH 121, from the same source. Near-infrared long-slit spectra confirmed the emission-line nature of the jets. The HH 121 bipolar jet emanates from the source at a large angle to the HH 111 jet and it is suggested that the source is a pre-main sequence-binary. Near-infrared lines were used to derive electron densities and extinction in parts of the HH 111 jet and an excitation temperature was derived from H2 lines.
