Airglow

Abstract

The past 4 years have seen the continuation of considerable activity in airglow research. Patterns of changing emphasis are becoming clear, observations are tending to become more selective, and changes in technique have led to regular observations of dayglow, line widths in the nightglow, and observations in the middle and far ultraviolet, detection and measurement of extremely faint emission lines, and the extension of the observed region well into the infrared.
