Abstract:

The report looks at the geomagnetic and ionospheric disturbances that were associated with solar flares on 25 and 27 September 1969. The terrestrial responses to these two solar events were considerably different. To better understand these differences, the events are related to some of the contemporary geophysical theories. The specific results of this study reinforce the general conclusions reached in previous ionospheric morphologies. The reason for the different F-region effects of these events appears to be dependent upon the pre-event magnetospheric conditions. Author
