We present CS(J=2-1) interferometric observations obtained with the Nobeyama Millimeter Array (NMA) toward a protostar (GH2O092.67 + 03.07) in the Cygnus OB7 giant molecular cloud (distance=800 pc). The data clearly indicate the presence of a compact (size ' 8 103AU) and young outflow with dynamical time scale ' 3500 year. The outflow is surrounded by a massive gas condensation. The analysis of...
