✦ Synopsis

We give a brief description of the Clark Lake Multifrequency Radioheliograph which is presently used for solar research in the frequency range 20-125 MHz. We present two-dimensional images of the Sun's corona at several frequencies within this range, obtained with time resolution as good as 1.28 s. The shape of the Sun's outer corona as observed at meter-decameter wavelengths appears to change in time periods as short as a few seconds.
