Short summary

Many independent observations have shown that long-period electromagnetic waves (with periods of several minutes) are preferably observed inside the auroral oval. Here we examine theoretically the possibility of Alfven wave generation by fluctuating large-scale field-aligned currents which couple outer space and the auroral ionosphere. The elaborated model indeed confirms the feasibility of an additional mechanism of long-period wave excitation which can operate at auroral latitudes.
