Observations of the General Background and Discrete Sources of 18·3 Mc/s Cosmic Noise

Abstract

A survey of a broad strip of the sky, centred on Dec. ?32°, has been made at a frequency of 18·3 Mc/s using an aerial with an overall beam width to half-power of 17°. Previous results concerning the background distribution of brightness have been confirmed and 37 discrete sources have been detected. The distribution of these sources shows some galactic concentration ; it becomes homogeneous if sources within 18° of the galactic plane are excluded.
