✦ Synopsis

The positional analysis of solar bursts at meter and decameter wavelengths observed during the period July 31-August 7, 1972 is presented. Most of the activity during this period was associated with the active regions McMath 11976 and 11970. Except near the CMP of region 11976, two regions of continuum emission were observed -one a relatively smooth continuum arm the other a continuum superimposed with many type III's and other fine structure. It seems possible to interpret these continua in terms of plasma waves originating from two sources located at different heights or with different electron density gradients. The angular size of type III sources seems to increase with decreasing frequency. This implies that the open field lines along which the type III electrons travel have larger angular extent at greater heights.
