We present radio line observations from the SEST. On the basis of ¹³CO(J=1-0) measurements we estimate the H₂ mass associated with the globules CG30/31A-C/38 to be ∼43M_☉. The gas kinetic temperature of the globules is in the range 5 to 14K. Line wings seen in the ¹²CO spectra as well as higher dipole moment molecules towards CG30, indicate that a dense molecular outflow is present. Especially the red wing reveals itself very clearly and is collimated, whereas the blue wing is weak and the emission is smeared out. The mass of the outflow is ∼0.3M_☉ and the dynamical time scale is 1.7x10⁴ years. The mechanical luminosity is 0.11L_☉ for an assumed inclination of 90°. The ¹³CO(J=1-0) data have revealed that CG30 is a possible double globule, the small companion (here named CG30B) having a mass of ∼25% of the larger globule, corresponding to ∼2M_☉.
