摘 要：We report an exohiss event in the low-density trough region observed by Van Allen Probes on 2February *** exohiss waves are discovered in the wide MLT distribution[9.1,13.4]and low magnetic latitude,with narrow-band structure and weak intensity compared with plasmaspheric *** the Continue Waveform Burst Mode data and MAG data on the EMFISIS,we analyze the normal angle,electromagnetic planarity and antiparallel-propagating Poynting flux of exohiss *** results show indicate that exohiss waves are the result of plasmaspheric hiss leakage into the trough
