Cosmic Noise Intensities at Hectometre Wavelengths
Abstract
The object of this contribution is to report the galactic background intensity at 2 and 3 MHz. The observation is an extension of earlier work which the noise temperatures at 50, 30, 20, 10 and 5 MHz were obtained at 65°N declination by means of identical antennas of beamwidth 70° between half-power points. As discussed in the earlier work, the temperatures were obtained separately in the ordinary and extraordinary modes, in order to account for the attenuation in the ionosphere.
