Extreme, transient bursts of energy in the auroral ionosphere. II. A magnetotail dipolarization event
New radar observations reveal extreme, transient energy bursts in the Earth's ionosphere during magnetospheric substorms.
Ground-based radar has detected unusually fast-moving, turbulent field structures in the auroral ionosphere, coinciding with a magnetotail dipolarization event.
These structures, identified as Farley-Buneman waves, moved significantly faster than expected, suggesting the presence of transient electric fields up to 330 mV/m.
The findings, supported by in-situ spacecraft data, offer new insights into the dynamics of energy transfer in the near-Earth plasma environment.
