Title: Interdisciplinary Investigations of the Auroral Phenomena
Abstract: Problems and difficulties of the interdisciplinary analysis of auroral phenomena can be discussed on the example of investigations in magnetically conjugate points. One such attempt was undertaken within the frame of Soviet-French cooperation in the field of space research. In March-April, 1968, a series of balloon launchings was performed in the northern (Arkhangelsk region) and southern (Kerguelen Island) conjugate subauroral zones (L ≈ 3.85). An interdisciplinary program was organized to observe the geophysical phenomena at the network of expeditionary stations in the environments of the conjugate points. During this experiment a better conjugacy was achieved than during all the other known flights of balloons (approximately 50 km). On the basis of calculations made by Roederer, the influence upon conjugacy has been estimated of the daily migration of conjugate points due to the change of spatial position of the geomagnetic-field axis. On the 1st of April, 1968, three events of auroral-electron precipitation were recorded. In the energetic spectrum of these electrons the presence of soft and hard components was revealed (characteristic energies 6 and 30 keV). In one of the events the presence of the maximum in the exponential spectrum near 90 keV (nearly monoenergetic flux of electrons) was revealed. Possibilities for the inter-correlated analysis of obtained data in comparison with satellite data (especially from ESRO-1) are discussed.
