Outline of Final Research Achievements |
In this study we have installed new loop antennas (100-kHz sampling) to measure VLF/ELF chorus waves and auroral cameras (30-100 Hz sampling) at subauroral latitudes in Canada since 17 February, 2012. These observations reveal several previously unknown features of VLF/ELF emissions and their relation to pulsating auroras at subauroral latitudes. Routine measurements of VLF/ELF and auroras have been carried out since then, and statistical features of VLF/ELF waves have been obtained at subauroral latitudes including their relation to local time, magnetic activity, and solar wind conditions. Comparisons with conjugate satellites in the magnetospheric equatorial plane are also on going.
