Determination of Topology Skeleton of Magnetic Fields in a Solar Active Region
Hui Zhao, Jing-Xiu Wang, Jun Zhang +2
The knowledge of magnetic topology is the key to understand magnetic energy release in astrophysics. Based on observed vector magnetograms, we have determined threedimensional (3D)…
Relationship between EIT Post Eruption Arcades, Coronal Mass Ejections, Coronal Neutral Line and Magnetic Clouds
Vasyl Yurchyshyn
There is observational evidence that the elongation of an Earth directed coronal mass ejection (CME) may indicate the orientation of the underlying erupting flux rope. In this stud…
Flow Field Evolution of a Decaying Sunspot
Na Deng, Debi Prasad Choudhary, Alexandra Tritschler +3
We study the evolution of the flows and horizontal proper motions in and around a decaying follower sunspot based on time sequences of two-dimensional spectroscopic observations in…
Two-Dimensional Spectroscopy of Photospheric Shear Flows in a Small delta Spot
C. Denker, N. Deng, A. Tritschler +1
In recent high-resolution observations of complex active regions, long-lasting and well-defined regions of strong flows were identified in major flares and associated with bright k…
Orientations of LASCO Halo CMEs and Their Connection to the Flux Rope Structure of Interplanetary CMEs
V. Yurchyshyn, Q. Hu, R. P. Lepping +2
Coronal mass ejections (CMEs) observed near the Sun via LASCO coronographic imaging are the most important solar drivers of geomagnetic storms. ICMEs, their interplanetary, near-Ea…
