Sažetak
The occurrence of metre-wave type III radio bursts was investigated in relation to the location of the associated flare in the magnetic field configuration for two periods of low solar activity in 1975--1977 and 1985--1987. In a statistical analysis it was found that for subflares the probability to produce a type III burst is higher by about one order of magnitude if the flare occurs at the boundary compared to a position elsewhere inside the general bipolar pattern of the related active region. The 3-D-topology of the magnetic field was calculated by extrapolation of the observed magnetic field for selected active regions and events. The locations at the border where the Hα -patches of flares associated with type III bursts were observed are close to open field lines extending high into the corona.
