Scientific paper

An object located approximately at l equals 8 deg, b equals -4 deg with a mean radial velocity of -212.3 km/sec has been observed in the 21-cm neutral hydrogen line. The mean weighted velocity dispersion is 11.2 km/sec and the total mass is estimated to be 190 R-squared(kpc) solar masses. We discuss possible interpretations of the origin and nature of this object. The most likely interpretation is that we observe an expanding object which has been ejected from the galactic nucleus.
