Popis:	The design of the East West arm of a multi-element interferometer for solar noise observations in the band 2650–2950 mhz at the Algonquin Radio Observatory, Lake Traverse, Ont., Canada, is outlined. The completed first stage consists of an array of thirty-two 3-meter reflectors extending over 212 meters. In the second stage, four reflectors will be arranged symmetrically about the array for polarization studies, while in the third stage four additional reflectors will be placed to the East to form a compound interferometer. These configurations provide single lobed fan beams with half power widths of 1.5, 0.5 and 0.25 of arc respectively. Scans of the sun taken on April 26th, 1966 with the 32-element array located two widely separated enhancements of radio emission, which produced a small gradual rise and fall burst on the solar patrol record.
