A description is given of recent high-resolution observations of the sun made at 80 MHz with the Culgoora radioheliograph. In many cases the sources of type I storms show bi-polar structure, the two components being spatially separated by about 3' arc and strongly circularly polarized in opposite se

β¦ Synopsis
Direct measurements by the Culgoora radioheliograph of the apparent source heights of type I and type III bursts at the solar limb are described. The average observed height is approximately the same for type I and type III sources. The heights are somewhat larger than previous estimates. After refraction effects are removed the present results give an electron density model for the source region below 3 R o with densities on the average between 8 and 10 times the values for corresponding heights in the quiet K-corona.

With our experiment on the satellite IMP-6 (Explorer 43) we are able to track the position of type III solar bursts in elevation as well as elongation. We do this by measuring the correlations between signals on an electric dipole antenna which is approximately normal to the plane of the ecliptic, a
