Journal ArticleDOI
A classification of dayside auroral forms and activities as a function of interplanetary magnetic field orientation
Per Even Sandholt,Charlie J. Farrugia,Joran Moen,Øystein Noraberg,Bjørn Lybekk,Torleif Sten,T. Hansen +6 more
TL;DR: In this article, a classification of auroral forms in the dayside high-latitude ionosphere, based on ground observations from Svalbard, is presented, and the time history of the basic magnetopause coupling modes is manifested in the day-side aurora.
Journal ArticleDOI
The solar flux influence on quiet time conductances in the auroral ionosphere
Joran Moen,Asgeir Brekke +1 more
TL;DR: In this paper, Hall and Pedersen conductances derived from EISCAT Common Program 1 (CP-1) data during half a solar cycle are presented. But the present results are in good agreement with the theoretical model calculations by Rasmussen et al. [1988] for solar minimum conditions.
Journal ArticleDOI
Direct Observations of the Evolution of Polar Cap Ionization Patches
Qing-He Zhang,Bei-Chen Zhang,Mike Lockwood,Hongqiao Hu,Joran Moen,J. Michael Ruohoniemi,Evan G. Thomas,Shun-Rong Zhang,Huigen Yang,Rui-Yuan Liu,Kathryn A. McWilliams,Kathryn A. McWilliams,J. B. H. Baker +12 more
TL;DR: The authors' observations show that modulation of nightside reconnection in the substorm cycle of the magnetosphere helps form the gaps between patches where steady convection would give a “tongue” of ionization (TOI).
Journal ArticleDOI
Space weather challenges of the polar cap ionosphere
TL;DR: In this paper, the SuperDARN convection model is used to track polar cap ionosphere patches backward and forward in time, which can be used to forecast its destination in the future.
Journal ArticleDOI
On the importance of interplanetary magnetic field B on polar cap patch formation
Q-H. Zhang,B-C. Zhang,R. Y. Liu,H.-G. Yang,H.-Q. Hu,Z-J. Hu,S.-L. Liu,M. W. Dunlop,Mike Lockwood,Ian McCrea,Joran Moen,Mark Lester +11 more
TL;DR: In this paper, a number of poleward moving events were observed between 1130 and 1300 UT on 11 February 2004, during periods of southward interplanetary magnetic field (IMF), while the steerable antenna of the European Incoherent Scatter (ESR) Svalbard radar and the Tromsø VHF radar pointed nearly northward at low elevation.
