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 ...Journal article
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 ...Journal article
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 ...Journal article
