Five new Herbig-Haro (HH) objects, HH 126 to HH 130, have been discovered in the L1641/M42 region from Schmidt plates and confirmed by low-dispersion spectroscopy. One of them, HH 126, appears to have shown a considerable change in its morphology in the last 30 yr. Another, HH 130, is close to HH2, and its morphology suggests that it may be related to HH2. Also, a pair of HH objects of very low excitation, HH 128 and HH 129, may be physically associated withy HH 41 and HH 42 to represent altogether a single outflow system. In addition, two of the HH objects, HH 61 and HH 83, recently reported by Reipurth and Graham (1988) and by Reipurth (1989), respectively, were independently found. One of them, HH 83, has an opti4cal jet and is shown to be driven by an embedded T Tauri star. The present low- and high-dispersion spectroscopy confirms generally the results obtained by Reipurth on this object, in particular, the velocity increase of the highly blueshifted gas along the jet.
