β¦ Synopsis
A statistical analysis on 220 impulsive microwave bursts showed a marked preference to occur in sunspots of type D, E and F (after Ztirich classification). Assuming a shock mechanism for accelerating electrons, this tendency seems to be related to the size of the magnetic loops.

We have grouped observed type III solar bursts according to the discrete frequencies of observation in the kilometrie wavelength range. For each group we have obtained the bursts' frequency of occurrence as a function of the heliographic longitude of the associated optical flares. We found that flar
