Remarkable in many respects radio-source Sagittarius B2 was investigated
in HI radio-line at wavelength 21 cm, OH lines at frequencies 1665 and
1667 MGz and H2CO absorption line at wavelength 6.2 cm.
These data have allowed us to create the dynamic model of the cloud
of gas, around this object.
The cloud of gas of diameter 40 pc rotates with the velocity 20 km/s
at it`s edge and therefore it is stable. For its stabilization
mass part 2.5E+5 mass of Sun is required, that corresponds
to data of the CO observations.
