Abstract
A survey has been made of the Cygnus region at a wave-length of 1.89 m. using a pencil beam 2° wide. The account of this survey has been divided into two parts. Part I deals only with the observations of the intense localized source Cygnus (1). The celestial coordinates and intensity of the source are given and are compared with the measurements obtained by other observers using interferometers. The intensity of the source was observed to fluctuate and the frequency of occurrence and the degree of fluctuation are given. It is shown that the apparent mean intensity of the source is not changed by more than 2 per cent by the presence of fluctuations.
