The coherence scale length of band-limited Pc3 pulsations in the ionosphere
Band-limited Pc-3 pulsations were observed on one day with pulsation magnetometers, photometers and in VLF activity at South Pole and simultaneously, electric field pulsations were observed in the ionospheric cusp using the PACE HF-Radar located at Halley Station, Antarctica. The electric field puls...

Band-limited Pc-3 pulsations were observed on one day with pulsation magnetometers, photometers and in VLF activity at South Pole and simultaneously, electric field pulsations were observed in the ionospheric cusp using the PACE HF-Radar located at Halley Station, Antarctica.
