|Abstract:||An analysis of the ISIS-VLF data detected by magnetometer in the auroral region of the magnetosphere has been carried out for VLF-saucers. The generation mechanism of VLF-saucers has been studied in terms of excitation of electrostatic cyclotron harmonic emission due to energetic ions and electrons in the magnetospheric plasma. The attenuation bands of VLF-saucers, as observed by ISIS-2 satellite, have been discussed and it is interpreted that the cyclotron absorption of low energy protons at harmonics of local proton-cyclotron frequencies may be the cause for attenuation bands in VLF-saucers.|
