Contemporaneous Appearances of Auroral Spiral and Transpolar Arc: Polar UVI Observations and Global MHD Simulations
Motoharu Nowada, Yukinaga Miyashita, Aoi Nakamizo +2
A local vortex-structured aurora and a large-scale transpolar arc (TPA) were contemporaneously observed by the Polar ultraviolet imager (UVI) during the late recovery phase of a su…
Energetic Electron Precipitation Occurrence Rates Determined Using the Syowa East SuperDARN Radar
Emma C. Bland, Noora Partamies, Erkka Heino +2
We demonstrate that the Super Dual Auroral Radar Network (SuperDARN) radar at Syowa station, Antarctica, can be used to detect high frequency radio wave attenuation in the D region…
Patch Size Evolution During Pulsating Aurora
N. Partamies, K. Bolmgren, E. Heino +3
We report both decreasing and increasing trends in the patch sizes during pulsating aurora events. About 150 pulsating auroral events over the Fennoscandian Lapland have been succe…
Cosmic Noise Absorption During Solar Proton Events in WACCM-D and Riometer Observations
Erkka Heino, Pekka T. Verronen, Antti Kero +2
Solar proton events (SPEs) cause large-scale ionization in the middle atmosphere leading to ozone loss and changes in the energy budget of the middle atmosphere. The accurate imple…
Statistical study of auroral omega bands
Noora Partamies, James M. Weygand, Liisa Juusola
The presence of very few statistical studies on auroral omega bands motivated us to test-use a semi-automatic method for identifying large-scale undulations of the diffuse aurora b…
