These are radio images of the sun, which were obtained using the first ACA 12-m antenna manufactured by Japan. In these images, white color indicates strong intensity of radio waves, while darker color lower intensity. Since the pattern changes day by day, we can find that these images show the daily rotation and the surface structure of the sun. These high quality radio images were obtained by an observation for 20 minutes using the high-performance antenna.
