VLF-Noise in the Dayside Polar Cusp

VLF-noise measurements at several Antarctic ground stations (Mirny, Sleightrain and Vostok) are used as diagnostic of the parameters of the solar wind particles penetrating in the polar cusp region. The observed results revealed the higher level radiation zone in the dayside polar cusp region (geoma...

Description
Summary:VLF-noise measurements at several Antarctic ground stations (Mirny, Sleightrain and Vostok) are used as diagnostic of the parameters of the solar wind particles penetrating in the polar cusp region. The observed results revealed the higher level radiation zone in the dayside polar cusp region (geomagnetic latitude ∿79°) when Kp≤3; two maxima of the daily intensity of VLF noise occur around 12 h and 18 h (local magnetic time). The coincidence in time of the VLF noise growth with soft electrons precipitation probability maxima indicates that VLF noise in the dayside polar cusp is generated by precipitating soft electrons.
