Furukawa et al. (2014) present new 12 CO and 13 CO (J=2-1 and J=1-0) observations of two molecular clouds made with NANTEN2 and the Mopra Telescope. The so-called “jet” and “arc” clouds are loacted toward the stellar cluster Westerlund 2, RCW49, and the TeV gamma-ray source HESS J1023-575. Furukawa et al. suggest that neither are physically linked with Westerlund 2 but are located at a greater distance around 7.5 kpc.
