Analysis of multiple satellite data has revealed a striking connection between K-H waves on the magnetopause, surface waves in the hot zone near the plasmapause, and auroral undulations.
The wave-like features in the pre-midnight ionosphere are not moving, vary strongly from day-to-day, and are often associated with the equatorial plasma bubbles, but their origin is still unknown.
Citizen scientists provided images of sub-auroral STEVE (Strong Thermal Emission Velocity Enhancements) showing fine-scale green features with narrow streaks propagating poleward toward STEVE.
A new modeling effort could change our understanding of auroral arc formation.
A new study finds that the ionospheric anomaly over the Weddell Sea is likely influenced by proximity to auroral energy input, rather than by tilting magnetic fields.
Scientists use sounding rockets to show that small oscillations in electric fields can be just as important for atmospheric Joule heating as the presence of the electric field itself.
