The H 1 cloud around the Sgr B2 gas--dust complex at +60 km/sec radial velocity has been observed with the RATAN-600 radio telescope in the 21-cm line with 2'.6 x 55' x 6.3 km/sec resolution. The cloud measures roughly-equal40 pc across; its H 1 mass is roughly-equal1.5 x 10/sup 3/ M/sub sun/ and it has a low kinetic temperature, <20 /sup 0/K. It is rotating as a unit with roughly-equal20 km/sec velocity at its edge, but radial motions of 5 km/sec or more are absent.
