A general analysis is presented for quasielectrostatic wave propagation at wave normal angles theta close to the resonance cone angle theta(R). A general dispersion equation is simplified and presented as a cubic equation with respect to squared refractive index N-squared. The solutions of this equation at theta close to theta(R) depend on the sign of the coefficient before N to the 6th, taken at theta = theta(R). A distinction is made between 'main mode' which reduces to the corresponding solution for a cold plasma when electron temperature tends to zero, and 'additional mode' which does not reduce to a cold plasma solution. The obtained analysis results are compared with the results of numerical analyses by Hashimoto et al. (1977), and Tokar and Gary, (1985), and are applied for determination of the direction of whistler-mode energy propagation and for estimating the energy of auroral electrons responsible for auroral hiss excitation. Interpretation of the observed frequency separation between attenuation bands at the harmonics of the proton gyrofrequency in saucer emissions is presented.
