Abstract

A large number of excellent far ultraviolet auroral images were obtained by the Canadian ultraviolet imager dual camera system on board the Swedish Viking satellite launched in 1986. The high spatial and temporal resolutions of the observations have been used very effectively in the continuing development of theories of auroral morphology. The images can also be used to infer approximate auroral energy deposition rates due to precipitating particles if the absolute sensitivities of the cameras are known. An in-flight calibration procedure is described in which ultraviolet stars are used as absolute radiation standards.
