Metric type-III burst asymmetry relative to simple bipolar active regions
Metric type-III solar radio burst positions are compared spatially and temporally to underlying active-region geometry. The positions of these radio bursts have an asymmetric location distribution relative to simple bipolar regions. The type-III bursts show a tendency to occur nearer the leading active region - an association shown before from type-III burst and magnetic-field-polarity measurements. The type-III burst also generally occur to the left of the outward- to inward-directed magnetic field. The asymmetry relative to the outward directed magnetic field has a sense that is consistent with a mechanism of type-III burst production that involves a pre-existing coronal current system situated between expanding closed and open magnetic field lines.
