STUDIES OF LOCAL MORPHOLOGY, STRUCTURE AND DYNAMICS OF AURORA.

Abstract

Research in the following areas is summarized: Interferometric measurements of the 5200/02 NI-doublet in the aurora; observations and experiments pertinent to auroral theories; variations in the doppler profile of H-alpha in aurorae; emissions in the VLF-band observed near the auroral zone, part I. occurrence of emissions during disturbances, part II. the physical properties of the emissions; excitation of A10 bands in the sunlit atmosphere and determination of the temperature from the distribution among the vibrational levels; current densities in visual auroras; variations in energy spectrum of auroral electrons detected by simultaneous observations with photometer and riometer; studies on the excitation of N2 and N2(+) bands in aurora; rapid movements of auroral rays; temperature measurements from N2(+) bands in aurora; spectrophotometric investigations of nightglow and aurora; and the construction and application of a four-channel photometer for auroral research.
