The authors propose a means by which the theory of drift instabilities can be extended to plasmas of arbitrary beta. The authors then specialize to the drift Alfven instability driven by an electron temperature gradient, proposed by Coroniti and Kennel 1970 to be a source of Pi-1 micropulsations on auroral lines of force. Even at relatively low beta, the full finite beta theory differs considerably from previous low beta theories, and produces better agreement with observation. Author
