    Description
    We present in this paper a review of electric emissions in the high frequency range (2-80 kHz) by the CLUSTER constellation crossing the outer plasmasphere at its perigee. During the considered event, dated 27th May 2003, the constellation separation was large (5000 km) and the geomagnetic activity high (Kp - 4 - 5). A large panel of natural emissions are observed, in particular non thermal continuum emissions (NTC) and electrostatic emissions related to fCe, where fce is the local electron gyrofrequency. Intense NTC emissions visible in the northern hemisphere can be related with simultaneous observations from the IMAGE satellite, informing about large scale beaming properties. We present details about equatorial emissions at (n+ 1/2) fce and emissions at (n+1.1) fce observed at higher latitude. Lastly, intense emissions near the local plasma frequency fp are observed within large scale density irregularities.
