Quasi‐electrostatic ELF/VLF chorus emissions immediately above the equatiorial half‐gyrofrequency, observed to propagate with wave normal angle (Ψ) within 0.4–1.2° of the resonance cone (Ψ r ) [ Muto et al ., 1987], are shown to efficiently resonate with 0.1–10 keV electrons. These waves may thus be important in driving the relatively low energy (<10 keV) component of pulsating aurorae and the morning‐side diffuse aurorae (∼1 keV).
