Simon, Michal Abstract We discuss the extensive observations of the Sun at 3.2-mm wavelength carried out during the summer of 1964 with a radio telescope of 3' beam width. An average brightness temperature of 6402 + 215 K was measured at the center of the solar disk. No consistent limb brightening was observed. Brightnesstemperature maps were made and are correlated with Ha photographs and magnetograms. Regions of enhanced 3 2-mm emission are shown to correlate well with Ha-active regions and regions of strong magnetic fields. Particularly high enhancements were observed in regions that later flared. One flare was observed but not from its beginning. No bursts were detected.
