Two surveys of the galactic background radiation at low frequencies have recently been made at Cambridge. At 38 Mc/s, a survey of the sky between declinations −20° and +70° has been made by Blythe [1] using a new type of pencil-beam aerial system. This instrument, consisting of an array 1200 feet long in an east-west direction together with a small movable aerial, used the principle of aperture synthesis to provide a beam 2°.2 × 2°.3 at the zenith increasing to 2°.2 × 7°.4 at an angle of 70 degrees from the zenith.
