Scientific paper

An extensive concentration of neutral hydrogen has been observed in the fourth galactic quadrant, with a mean radial velocity of plus 44 km/s referred to the local standard of rest. At a distance of R kpc from the sun, this structure would contain 25,000 times R-squared solar masses of neutral hydrogen. Five possible interpretations of this extensive concentration are considered: (1) part of the shell of a nearby explosive event, (2) a distant spiral arm of the Galaxy, (3) an extragalactic object, (4) material falling into the Galaxy, and (5) gas expelled from the galactic center. Arguments are offered against the first three possibilities.
