Abstract
OBSERVATIONS made at Cambridge with a new interferometric radio telescope1 working on a wavelength of 3.7 m. have shown the existence of an intense radio source of large diameter in the constellation of Gemini. This source (06.01) had been detected in a previous survey2 with an interferometric arrangement; but it had not been possible to determine its position accurately, partly because the resolving power was too great to give a good response with a source of this size and partly because the gain of the aerial was too small. In the present investigation, observations were made with a number of different resolving powers, and it was possible to determine both the position of the source and the distribution of brightness across it.
