Abstract : The instrument currently in use for the spectroscopic and photometric observation of aurora and airglow are listed together with modifications and new developments of instrumentation. Modifications have been made to a two channel rocket-borne photometer that is used for measuring 1.27 micrometer radiation. A birefringent photometer has been modified to make it more useful for twilight measurements. Investigations have been carried out on the rotational temperatures derived from OH emissions. Further observations of 1.27 micrometer oxygen emission have been made from both the ground and rocket flights. These measurements and others have been analysed so that many of the temporal and spatial properties of this emission are now known. An auroral component of this emission has also been investigated. Considerable theoretical investigations have been carried out on the photochemistry of oxygen and hydrogen to accompany the measurement of the OH and 1.27 micrometer O2 emissions. Hydrogen and atomic oxygen emissions have been measured in a hydrogen auroral arc. The results of analysis on a decade of twilight sodium density measruements are presented. (Author)
