摘要：Previous observations indicate that there are mainly unstructured plasmaspheric hiss in the high-density plasmasphere, whereas structured whistler mode chorus waves with the lowest frequency of 0.1fce (fce is the electron gyrofrequency) are observed mostly outside the plasmapause. Here we observed ultrawideband rising-tone chorus waves with frequencies extending to lower hybrid resonance frequency (fLHR ~ 101 Hz) in a dawnside high-density region (magnetic local time [MLT] ~ 7 hr and Ne ~ 75 cm 3) inside the oscillating plasmapause. The ultrawideband chorus waves have also typical two-band str
