Scientific paper

Molecular gas at -190 km/s discovered by Gusten & Downes (1981) is found to extend some 0.2 deg (30 pc) near Sgr A* in a kinematically simple but somewhat fragmentary shell centered just to the west of the Galactic center. Most likely, the material is located on the near side of the extended, tilted, inner-galaxy molecular gas disk and associated with emission from the so-called 'expanding molecular ring' at -135 km/s. Thus it is distant from and unrelated to phenomena occurring near Sgr A* itself. The mass of molecular material is estimated as MH2 = 10 exp 5 solar masses.
