Extreme, transient bursts of energy in the auroral ionosphere. II. A magnetotail dipolarization event
Magnus F Ivarsen, Yukinaga Miyashita, Brian Pitzel +5
We report ground-based coherent VHF radar observations of extreme turbulent field-structures detected in coincidence with a magnetospheric substorm-associated magnetotail dipolariz…

Extreme, transient bursts of energy in the auroral ionosphere. I. Predictive radar tracking
Magnus F Ivarsen, Jean-Pierre St-Maurice, Devin R Huyghebaert +7
Three-metre Farley-Buneman irregularities observed by the \textsc{icebear} VHF radar organize into clusters whose apparent motion follows the electric field mapped from the magneto…

Excursion-set structure factor of the auroral electric field
Magnus F Ivarsen, Kaili Song, Jean-Pierre St-Maurice +1
We treat coherent radar echoes from aurorae as a finite point process and measure its structure factor from pairwise echo separations. Backscatter requires electron drifts t…
