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…
The Eruption from a Sigmoidal Solar Active Region on 2005 May 13
Chang Liu, Jeongwoo Lee, Vasyl Yurchyshyn +4
This paper presents a multiwavelength study of the M8.0 flare and its associated fast halo CME that originated from a bipolar active region NOAA 10759 on 2005 May 13. The source ac…
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…
Topological changes of the photospheric magnetic field inside active regions: a prelude to flares
L. Sorriso-Valvo, V. Carbone, V. Abramenko +5
The observations of magnetic field variations as a signature of flaring activity is one of the main goal in solar physics. Some efforts in the past give apparently no unambiguous o…
