The Earth's auroral electrons produce copious non-thermal radio emissions of various types,
including auroral kilometric radiation (AKR), whistler mode auroral hiss, mode conversion …

The present 15th volume of the ISSI Space Science Series is devoted to Auroral Plasma
Physics. The aurora is arguably the most intriguing phenomenon in space plasma physics …

Many advances in understanding space plasma phenomena have been linked to insight
derived from theoretical modeling and/or laboratory experiments. Advances for which …

Using observations from the FAST small explorer spacecraft, we present fields and plasma
observations above the dayside auroral oval showing the erosion of ionospheric plasmas …

The subject of lower-hybrid solitary structures (LHSS), sometimes called lower-hybrid
cavities, is reviewed. LHSS are spatially localized structures embedded in space plasmas …

Heavy (O+) ion energization and field‐aligned motion in and near the ionosphere are still
not well understood. Based on observations from the CAScade, Smallsat and IOnospheric …

Abstract The Suprathermal Electron Imager (SEI) on the Enhanced Polar Outflow Probe (e-
POP) experiment uses a microchannel-plate-intensified charge-coupled device (CCD) …

Two sequences, before and after magnetic noon, respectively, of poleward moving auroral
forms with associated upflows situated above the European Incoherent Scatter Svalbard …

We describe a new class of nonthermal plasma density irregularities observed in the
postmidnight topside equatorial ionosphere under low solar flux conditions. They are distinct …

The SERSIO sounding rocket was launched from Ny‐Alesund, Svalbard, into a type 2 ion
upflow event simultaneously observed by the European Incoherent Scatter (EISCAT) radar …
