Popis:	Detailed observations of the Cygnus X region have been obtained at a frequency of 3200 Mc/s using the 10-metre parabolic reflector of the National Research Council of Canada. The resultant contour map shows this region to be very complex, having more than thirty bright condensations. A flux density has been computed for each and an angular size has been estimated for all sources larger than twenty minutes of arc. A derived spectral index of -04 and its large angular size lead to the hypothesis that this source is the remnant of a type II supernova at a distance of 300-1650 parsecs.
