Abstract : A continuous scanning technique has been developed to make complete 3.3-mm maps of the sun in 4.5 min with an antenna having a half-power beamwidth of 2.8 arc-min. A computer program that generates 35-mm photographs from the matrix of radiometric readings is described. Time lapse films of 3.3-mm sun maps with a time resolution of several minutes can be made. Consequently, studies of the rapid time development of active regions at millimeter wavelengths are now possible. (Author)
