Fine-scale dynamics of fragmented aurora-like emissions
Abstract ∘ N). The FAEs are only visible in certain emissions, and their shape has no magnetic-field-aligned component, suggesting that they are not caused by energetic particle precipitation and are, therefore, not aurora in the normal sense of the word. The FAEs sometimes form wave-like structures parallel to an auroral arc, with regular spacing between each FAE. They drift at a constant speed and exhibit internal dynamics moving at a faster speed than the envelope structure. The formation mechanism of FAEs is currently unknown. - 1 - 1 - 1 is required to produce the observed speeds of the FAEs; such a strong electric field may be a requirement for FAEs to occur.
