Brief Description (Abstract):

Observation of VLF/ELF emissions at high latitude is attributed to the lightning, thunderstorm activities and power line radiations solar flares, at high latitudes. Contribution due to solar particle fluxes becomes important for VLF/ELF discrete emissions. The discrete auroral structures which may be generated by wave particle interactions between up and down-going energetic electrons and magnetospheric electric current generally observed at high latitudes. Discrete inverted-V shaped emissions shows a close association with auroral precipitation and these emissions are observed at ground station with a multiple structure and fading characteristic resulting from an ionospheric and/or magnetospheric mechanism of stratification.

Status: Completed

Purpose: Very low frequency (VLF) (ionospheric noise) and Extremely low frequency (ELF) emissions, a class of naturally emitting radio phenomena very important diagnostic tool for probing the plasmasphere and beyond. VLF emissions are appear in wide variety of spectral forms and it may appears in short burst to several minutes or hours.
