Linking two consecutive non-merging magnetic clouds with their solar sources
(American Geophysical Union, 2009-12)
On 15 May 2005, a huge interplanetary coronal mass ejection (ICME) was observed near Earth. It triggered one of the most intense geomagnetic storms of solar cycle 23 (Dstpeak = −263 nT). This structure has been associated ...
Model-independent large-scale magnetohydrodynamic quantities in magnetic clouds
(Elsevier, 2005-12)
Magnetic clouds are the interplanetary manifestation of coronal mass ejections, which are transient expulsions of major quantities of magnetized plasma, from the Sun toward the heliosphere. The magnetic flux and helicity ...
20 Years of ACE Data: How Superposed Epoch Analyses Reveal Generic Features in Interplanetary CME Profiles
(Blackwell Publishing Ltd, 2020-10)
Interplanetary coronal mass ejections (ICMEs) are magnetic structures propagating from the Sun's corona to the interplanetary medium. With over 20 years of observations at the L1 libration point, ACE offers hundreds of ...

Expansion of magnetic clouds in the outer heliosphere
(EDP Sciences, 2012-04)
Context. A large amount of magnetized plasma is frequently ejected from the Sun as coronal mass ejections (CMEs). Some of these ejections are detected in the solar wind as magnetic clouds (MCs) that have flux rope signatures. ...
Global and local expansion of magnetic clouds in the inner heliosphere
(EDP Sciences, 2010-01)
Context: Observations of magnetic clouds (MCs) are consistent with the presence of flux ropes detected in the solar wind (SW) a few days after their expulsion from the Sun as coronal mass ejections (CMEs). Aims: Both the ...
Determining the solar source of a magnetic cloud using a velocity difference technique
(Springer, 2011-01)
For large eruptions on the Sun, it is often a problem that the core dimming region
cannot be observed due to the bright emission from the flare itself. However, spectroscopic data can provide the missing information through ...
Dynamical evolution of a magnetic cloud from the Sun to 5.4 AU
(EDP Sciences, 2011-07)
Context. Significant quantities of magnetized plasma are transported from the Sun to the interstellar medium via interplanetary coronal mass ejections (ICMEs). Magnetic clouds (MCs) are a particular subset of ICMEs, forming ...
Magnetic cloud models with bent and oblate cross-section boundary
(EDP Sciences, 2009-09-15)
Context. Magnetic clouds (MCs) are formed by magnetic flux ropes that are ejected from the Sun as coronal mass ejections. These structures generally have low plasma beta and travel through the interplanetary medium interacting ...
