Although their main sourcelocation is well identified for Earth in the vicinity of the equatorial plasmapause andits generation mechanism generally associated with electrostatic emissions arisingbetween half harmonics of the electron gyro harmonics, many details of theircharacteristics and source are still missing. Recent observations had suggested newfeatures in their description. For example, studies based on the Whisperinstruments have shown that continuum sources can also be located at mid latitudesand can be generated at exact harmonics of the electron frequency. The higherperigee of the present phase of the Cluster extended mission allows the spacecraftto skim the sources regions close to the plasmapause and to explore their latitudinalextension thanks to its polar orbit. This higher perigee also allows to get Peace data,seldom available at the lower perigees earlier in the mission, to characterize theelectrons populations at the origin of these emissions. We present here the firstanalysis of the best events observed so far. %G English %L hal-02993253 %U https://hal-cnrs.archives-ouvertes.fr/hal-02993253 %~ OBSPM %~ INSU %~ X %~ CNRS %~ UNIV-ORLEANS %~ CNES %~ X-LPTP %~ X-DEP %~ X-DEP-PHYS %~ OSUC %~ LPC2E %~ PSL %~ UNIV-PARIS-SACLAY %~ SORBONNE-UNIVERSITE %~ SORBONNE-UNIV %~ SU-SCIENCES %~ X-LPP %~ IP_PARIS %~ IP_PARIS_COPIE %~ LABORATOIRE-DE-PHYSIQUE-DES-PLASMAS-LPP %~ LPP-PLASMAS-SPATIAUX %~ LPP-INFORMATIQUE %~ TEST-HALCNRS %~ OBSPM-PSL %~ GS-PHYSIQUE %~ INSTITUT-SCIENCES-LUMIERE %~ ALLIANCE-SU
