TL;DR: The conductance enhancement associated with precipitating electrons not only modified the electric field within the aurora but also affected the generation of small‐scale plasma structures in the vicinity of the patch‐type optical auroral forms.
Journal ArticleDOI
Fine‐scale transient arcs seen in a shock aurora
TL;DR: In this paper, fine-scale transient arcs that emerged successively within the initial 1-2 min evolutionary interval of a postnoon shock aurora on 14 July 2012 were reported.

TL;DR: In this paper, a case study of a day-time Pc3 (22-100 mHz) auroral pulsation event, measured with a ~2'Hz sampling all-sky camera at South Pole Station (74.4°S magnetic latitude) on 17 May 2012, is presented.
