Fragments are detected in the outer parts of the B209 molecular cloud in a region of density 1000 cm−3 using 12CO, 13CO, H2CO, IRAS 60 and 100 µm images, discernable as velocity components, and have characteristics: ∼ 0.4 Pc; ∼2 M⨀;#x003C;MVRfragment>∼ 1.6 M⨀ km/s pc; Tgas ∼11 K; Tdusat ∼ 16 K??.The system of fragments has ∼ 0.5 pc and ∼ 1.6 M⨀ km/s pc.These are illustrated in Figure 1, which contains an IRAS 100 µm map made with Geisha and attendant U. Koln Gornergrat CO spectra for each respective fragment. The differing characteristic velocities of each fragment are readily apparent.
