This work shows preliminary results on the study of the sinusoidal HH 31 jet and its driving source, the low-mass Class I protostar IRAS 04248+2612, located in the Taurus-Auriga star-forming region. In particular, we report progress on the analysis of high-angular resolution Gemini/NIRI 2.12 μm H2 line (a well-known tracer of shockexcited regions) images with the aim of detecting the near-infrared(NIR) counter-jet of HH 31 which could be embedded or optical hidden by the cloud extinction.
