This paper contains an account of the discovery of, and subsequent work on, one of the minor discrete sources of galactic radio-frequency noise-Taurus-A. Full details are given of observations and calculations leading to the determination of the source's position and its probable identification with the Crab nebula or supernova of A.D. 1054.

Frequency Radiation

An account is given of observations on a number of discrete sources of radio- frequency radiation, together with a brief description of the observational techniques used in their detection, and of the methods employed to determine their positions and angular extent.Noise spectra of four of the more intense sources have been measured over a frequency range of 40-160 Mc/s. : in three cases the change of intensity with wave- length is found to be greater than that of the background continuum, and in one case less. Two of the sources have been provisionally identified with astronomically rare objects, the Crab Nebula and N.G.C. 5128.Finally, the short period fluctuations in the intensity of some of the sources, notably that in Cygnus, are discussed. Evidence is presented which, contrary to previous views, suggests that these fluctuations are of terrestrial rather than of extra-terrestrial origin.

Frequency Radiation

An account is given of investigations on a strong variable source of radio frequency energy in the constellation of Cygnus, including a determination of the size and celestial coordinates of the source and a study of the variations over a frequency range from 60 to 200 Mc/s. The frequency spectra are compared with those of galactic and solar radiation. The position of the source is found to be in a region of relatively low stellar density and not coinciding with an outstanding stellar object. A discussion of limits of distance and possible nature of the source is given.
