Tracking the Evolution of A Coherent Magnetic Flux Rope Continuously from the Inner to the Outer Corona
X. Cheng, M. D. Ding, Y. Guo +6
The magnetic flux rope (MFR) is believed to be the underlying magnetic structure of coronal mass ejections (CMEs). However, it remains unclear how an MFR evolves into and forms the…
Investigating Two Successive Flux Rope Eruptions In A Solar Active Region
X. Cheng, J. Zhang, M. D. Ding +4
We investigate two successive flux rope (FR1 and FR2) eruptions resulting in two coronal mass ejections (CMEs) on 2012 January 23. Both FRs appeared as an EUV channel structure in…
Secondary Waves, and/or the "Reflection" From and "Transmission" Through a Coronal Hole of an EUV Wave Associated With the 2011 February 15 X2.2 Flare Observed With SDO/AIA and STEREO/EUVI
Oscar Olmedo, Angelos Vourlidas, Jie Zhang +1
For the first time, the kinematic evolution of a coronal wave over the entire solar surface is studied. Full Sun maps can be made by combining images from the Solar Terrestrial Rel…
Investigation of the Formation and Separation of An EUV Wave from the Expansion of A Coronal Mass Ejection
X. Cheng, J. Zhang, O. Olmedo +3
We address the nature of EUV waves through direct observations of the formation of a diffuse wave driven by the expansion of a coronal mass ejection (CME) and its subsequent separa…
