Abstract : Several improvements have been made to the Mt. Wilson Observatory solar magnetograph, including changes to the guider, the Doppler compensator, and the data handling system. The improved magnetograph has been used for a new type of solar observation consisting of several hundred scans back and forth along a straight line of length 3/4 R sub o perpendicular to central meridian. The data reduction, which is done entirely with a computer, eliminates those effects which have their origin in the earth-sun geometry. The spatial and temporal properties of the 5-minute oscillations are discussed. (Author)
