General description of a ring-like molecular structure discovered in the G332 sector, located at a V(lsr) = ~ -50 km/s with a minimum spectral width of ~7 km/s, at a distance of 3.7 kpc from Earth. The ring is observed in the 12CO, 13CO, C18O lines of the MopraCO Survey, and in the CI line measured from the HEAT telescope in Antarctica. Deeper investigation are ongoing to better characterise the physics of the ring and the related features interacting with the molecular structure
