The Rise and Emergence of Untwisted Toroidal Flux Ropes on the Sun
Kalman J. Knizhnik, James E. Leake, Mark G. Linton +1
Magnetic flux ropes (MFRs) rising buoyantly through the Sun's convection zone are thought to be subject to viscous forces preventing them from rising coherently. Numerous studies h…
Sequential eruptions triggered by flux emergence - observations and modeling
Sally Dacie, Tibor Torok, Pascal Demoulin +5
We describe and analyze observations by the Solar Dynamics Observatory of the emergence of a small, bipolar active region within an area of unipolar magnetic flux that was surround…
Observations and Modelling of the Pre-Flare Period of the 29 March 2014 X1 Flare
M. M. Woods, L. K. Harra, S. A. Matthews +3
On the 29 March 2014 NOAA active region (AR) 12017 produced an X1 flare which was simultaneously observed by an unprecedented number of observatories. We have investigated the pre-…
Evolution of the Magnetic Field Distribution of Active Regions
Sally Dacie, Pascal Démoulin, Lidia van Driel-Gesztelyi +5
Aims. Although the temporal evolution of active regions (ARs) is relatively well understood, the processes involved continue to be the subject of investigation. We study how the ma…
Flux cancellation and the evolution of the eruptive filament of 2011 June 7
S. L. Yardley, L. M. Green, D. R. Williams +3
We investigate whether flux cancellation is responsible for the formation of a very massive filament resulting in the spectacular 2011 June 7 eruption. We analyse and quantify the…
Solar Influence on the North Atlantic Oscillation - Initial Results
Sally Dacie
Some initial investigations into various atmospheric phenomena and the influence of the solar cycle on weather have been made. Strongly negative North Atlantic Oscillation (NAO) in…
