8·8 GHz Radio Observations of 12 Suggested Supernova Remnants

Abstract

Brightness distributions and flux densities at 8·8 GHz are presented for 12 small-diameter radio sources near the galactic plane. Each of these sources has been classified at one time or another as a supernova remnant. For one source, G295· 2 - 0·6, the flux density at 8·8 GHz confirms the thermal spectrum suggested by lower frequency measurements and indicates that it is not a supernova remnant. Another source, G309· 6+ 1·7, is thought to be extragalactic.
