Abstract : During June, 1959, observations were made of the occultation of the Crab nebula by the solar corona at the Clark Lake radio astronomy station. The observing frequency was 26.3 mc/sec (11.4m wavelength). These observations extend the work of other observers to this lower frequency. Effects due to the scattering of radio waves in the solar corona have been found to a distance of 25 solar radii. These results are in agreement with those of other observers when scaled to their frequencies; however, they extend the observations to larger distances from the sun than those over which effects have previously been observed.
