We investigate a relatively unstudied star formation region in Cygnus centered on RNO 127, finding numerous Herbig-Haro flows, many identified in optical [SII], Hα , and near-infrared H2 tracers of shock waves. Several protostars and young stars are thus located, including one conspicuously brightened object, which illuminates a variable reflection nebula. In total, the coordinates of 17 optical HH knots and jets, 4 associated cometary nebulae and 3 NIR objects are given. Individual structures are discussed including a central complex which has the characteristics of superposed HH flows. This star-forming cloud is not isolated but is part of a much larger region of distributed star formation, including HH 380 and HH 381.
Based on observations collected at the Byurakan Astrophysical Observatory, Byurakan, Armenia. Includes observations made at German-Spanish Astronomical Centre, Calar Alto, operated by the Max-Planck-Institut für Astronomie.
