A star close to HH 1 is a bright infrared source. Its optical spectrum shows it to be a highly obscured T Tauri star. It is argued that this is the source of excitation of HH 1, and perhaps also of HH 2. The likely mass-loss rate is of the order of 10 to the -8th to 10 to the -7th solar mass/yr, depending on the geometry of outflow from the star. Another infrared object may contribute to the excitation of HH 2.
