Abstract
The interdependence of ionospheric disturbances and large solar flares is examined for a four year period near sunspot maximum. It is shown that those flares that are accompanied by major noise bursts at frequencies below 200 mc/s are followed in a period of less than four days by noticeable ionospheric disturbances, while no such association is found for those flares not accompanied by major bursts at the lower radio frequencies. For the burst-accompanied flares, it is shown that the magnitude of the terrestrial disturbance depends strongly on the location of the flare on the sun. The nature of this dependence is discussed in terms of a model of the solar magnetic field.
