Sympathetic Partial and Full Filament Eruptions Observed in One Solar Breakout Event
, 2012 We report two sympathetic solar eruptions, including a partial and a full flux rope eruption in a quadrupolar magnetic region, where a large and a small filament resided above the middle and the east neutral lines respectively.

Initiation of coronal mass ejections [PDF]
, 2006 This paper is a synopsis of the initiation of the strong-field magnetic explosions that produce large, fast coronal mass ejections. Cartoons based on observations are used to describe the inferred basic physical processes and sequences that trigger and drive the explosion. The magnetic field that explodes is a sheared-core bipole that may or may not be

Implications of Using Spheroidal “Cone Model” CMEs in Solar‐Wind Models
Space Weather, Volume 23, Issue 6, June 2025.Abstract Space‐weather forecasting requires advanced prediction of the arrival time and properties of coronal mass ejections (CMEs) in near‐Earth space. Kinematic properties of CMEs close to the Sun—such as speed, direction and angular width—are routinely estimated from coronagraph images by using three‐dimensional geometric models, such as the “cone ...

Multi-thermal dynamics and energetics of a coronal mass ejection in the low solar atmosphere [PDF]
, 2012 Aims. The aim of this work is to determine the multi-thermal characteristics and plasma energetics of an eruptive plasmoid and occulted flare observed by the Solar Dynamics Observatory’s Atmospheric Imaging Assembly (SDO/AIA). Methods.

, 2010 On 5 April 2010 an interplanetary (IP) shock was detected by the Wind spacecraft ahead of Earth, followed by a fast (average speed 650 km/s) IP coronal mass ejection (ICME).

Observations of Coronal Mass Ejections [PDF]
Proceedings of the International Astronomical Union, 2006 National Astronomical Observatory, Chinese Academy of Sciences, Beijing, Chinaemail: wang@ourstar.bao.ac.cnAbstract. Observations of source regions of coronal mass ejections have progressed enormouslyin the past decade with the observations from SOHO and Yohkoh.

Reduced ERA‐I Forecasting Skill During Forbush Decreases
Geophysical Research Letters, Volume 52, Issue 10, 28 May 2025.Abstract Correlations between week‐long cosmic ray flux perturbations and terrestrial cloud cover have previously been identified. Still, uncertainty persists on whether the cloud response is due to a physical link involving cosmic rays or caused by random weather fluctuations.

, 2006 [1] The Solar Mass Ejection Imager (SMEI) has been tracking coronal mass ejections (CMEs) from the Sun to the Earth and beyond since it came online in February 2003.

The Astrophysical Journal, 2001 Narrow coronal mass ejections (CMEs), defined arbitrarily as events whose apparent angular width is 15° or less, are a small subset of all CMEs. Little is known of the properties of these events and whether these properties differ from those of the larger, more typical CMEs. We have included in this study 15 narrow CMEs observed in the period from 1999
