ResumoWe show that whistler mode noise generated inside mirror modes (Lion Roars) by a remaining electron temperature anisotropy may become trapped in the mirror bottle. The trapping selects a narrow range of wave numbers and restricts the width of the lion roar frequency band in agreement with recent observations.
