Abstract

The construction and operation of a high resolution interferometer for solar noise observations at 10.7 cm for the Algonquin Radio Observatory is described. One element is the existig 32 element array of 3 m reflectors while the second is a grating element of 4 reflectors symmetrically placed on the same E-W line. The aperture of 665 m produces a fan beam of 0.5′ E.W. by 2° N.S. Four Faraday rotators in the antenna feeds of the newly commissioned grating enable three Stoke's parameters to be observed. The expected antenna pattern is confirmed by making observations on the brighter radio sources. Observations of the Sun on 1972, January 6 show the range of phenomena to be observed and a detailed study of the association of eight radio emissive regions with all centers of solar activity is presented.
