    • On the Persistent Shape and Coherence of Pulsating Auroral Patches 

      Humberset, Beate Krøvel; Gjerløv, Jesper; Mann, Ian R.; Michell, Robert; Samara, Marilla (American Geophysical Union, 2018-05)
      The pulsating aurora covers a broad range of fluctuating shapes that are poorly characterized. The purpose of this paper is therefore to provide objective and quantitative measures of the extent to which pulsating auroral ...

    • Scale size-dependent characteristics of the nightside aurora 

      Humberset, Beate Krøvel; Gjerløv, Jesper; Samara, Marilla; Michell, Robert (Wiley, 2017-02)
      We have determined the spatiotemporal characteristics of the magnetosphere-ionosphere (M-I) coupling using auroral imaging. Observations at fixed positions for an extended period of time are provided by a ground-based ...

    • Temporal characteristics and energy deposition of pulsating auroral patches 

      Humberset, Beate Krøvel; Gjerløv, Jesper; Samara, Marilla; Michell, Robert; Mann, Ian R. (Wiley, 2016-07-23)
      We present a careful statistical analysis of pulsating aurora (PA) using all-sky green line (557.7 nm) images obtained at 3.3 Hz. Six well-defined individual PA patches are identified and extracted using a contouring ...
