Interferometer observations of three highly interesting 18-cm line sources gave an upper limit of 20 seconds of arc for their diameter. Therefore their brightness temperature must be at least 500,000K. Accurate positions for two objects were obtained. There might be a relation between the interstellar ionized hydrogen gas and the position of one of the sources. Author
