Abstract : The Faraday rotation data were collected a Cold Bay, Alaska in an effort to correlate with similar data collected at Invercargill, New Zealand. Cold Bay and Invercargill form an approximate conjugate pair. Day-to-day variations of content at these two stations have been compared and studied. It has been found that these changes were negatively correlated during periods of magnetic quiet, uncorrelated during weak magnetic activities and increasingly positively correlated with increasing magnetic activities. In the second experiment two field stations were set up along the path of March 7, 1970 solar eclipse. These data, when combined with data obtained by others, show that the delay between the time of maximum obscuration and the time of minimum content varies systematically with latitude. The theoretical study is concerned with studying the effect of a dynamo electric field on the thermospheric winds. (Author)
