Abstract

Intense and localized burst of electrostatic emissions have been observed by the Whisper instrument on Cluster at frequency close to the electron plasma frequency, in the magnetopause boundary layer. The good time resolution of Whisper when in burst mode telemetry as well as the combination of the observations performed by the four Cluster spacecraft at short separation distance (∼100 km) have allowed to determine in one case the dimension of these structure, typically a few tens of kilometers, close to the electron scale. We browse Whisper data in search for such events and present here some examples of their observations. We present the main characteristics of the spectra and power profile of the emissions.
