Abstract
A synthesis map obtained with the Cambridge Half-mile telescope shows that the galactic radio source G127.1 + 0.5 has a shell structure; in conjunction with other data we conclude that it is probably an old supernova remnant. Near the centre of the shell the map shows a compact radio source whose angular size, measured at 15 GHz with the 5-km Cambridge telescope, is less than 0.15 arcsec, and whose spectrum is very flat. We suggest that the compact source may be the stellar remnant of the supernova.Keywords
