Core ion interactions with BB ELF, lower hybrid, and Alfvén waves in the high-latitude topside ionosphere

We present simultaneous observations of ion distribution functions and plasma waves in the high‐latitude topside ionosphere (500–1000 km) near local midnight during substorm activation. Using a new instrument, the Suprathermal Ion Imager (SII), we are able to explore two‐dimensional ion distribution...

Zusammenfassung:	We present simultaneous observations of ion distribution functions and plasma waves in the high‐latitude topside ionosphere (500–1000 km) near local midnight during substorm activation. Using a new instrument, the Suprathermal Ion Imager (SII), we are able to explore two‐dimensional ion distribution functions with unprecedented resolution in time (93 s−1) and energy, focusing on the lowest‐energy core (
