Abstract : Several hundred ion whistlers recorded by the VLF receiver in the Alouette II satellite during its first year in orbit have been analyzed. These whistlers were observed over nearly the full height range of the satellite from 500 km to 3000 km, and at invariant latitudes up to 67 degrees. They have provided considerable information on the relative abundance of hydrogen, helium and oxygen ions in this region. (Author)
