We demonstrate that major asymmetries in erupting filaments and CMEs, namely major twists and non-radial motions are typically related to the larger-scale ambient environment around eruptive events. Our analysis of prominence eruptions observed by the STEREO, SDO, and SOHO spacecraft shows that prominence spines retain, during the initial phases, the thin ribbon-like topology they had prior to the eruption. This topology allows bending, rolling, and twisting during the early phase of the… 

Observations of Photospheric Vortical Motions During the Early Stage of Filament Eruption

Solar filaments/prominences exhibit rotational motion during different phases of their evolution from their formation to eruption. We have observed the rotational/vortical motion in the photosphere

Filament Eruption Driving EUV Loop Contraction and Then Expansion above a Stable Filament

We analyze the observations of EUV loop evolution associated with the filament eruption located at the border of an active region (AR). The event SOL2013-03-16T14:00 was observed with a large

Twisting/Swirling Motions during a Prominence Eruption as Seen from SDO/AIA

A quiescent prominence was observed at the northwest limb of the Sun using different channels of the Atmospheric Imaging Assembly on board the Solar Dynamics Observatory. We report and analyze

“Twisting” Motions in Erupting Coronal Pseudostreamers as Evidence for Interchange Reconnection

Using white-light observations from the COR1 coronagraph during 2008–2013, we have identified ∼50 eruptive events in which a narrow streamer structure appears to rotate about its radial axis as it

Prominence and Filament Eruptions Observed by the Solar Dynamics Observatory: Statistical Properties, Kinematics, and Online Catalog

We present a statistical study of prominence and filament eruptions observed by the Atmospheric Imaging Assembly (AIA) onboard the Solar Dynamics Observatory (SDO). Several properties are recorded

Magnetofrictional Modeling of an Erupting Pseudostreamer

In this study, we present the magnetic configuration of an erupting pseudostreamer observed on 2015 April 19, on the southwest limb of the Sun, with a prominence cavity embedded inside. The eruption

Polarity relevance in flux-rope trajectory deflections triggered by coronal holes

Context. Many observations suggest that coronal holes (CHs) are capable of deviating the trajectory of coronal mass ejections (CMEs) away from them. However, for some peculiar events, the eruption

Modeling a Coronal Mass Ejection from an Extended Filament Channel. I. Eruption and Early Evolution

We present observations and modeling of the magnetic field configuration, morphology, and dynamics of a large-scale, high-latitude filament eruption observed by the Solar Dynamics Observatory. We

Pseudostreamer influence on flux rope evolution

Context. A highly important aspect of solar activity is the coupling between eruptions and the surrounding coronal magnetic field topology, which determines the trajectory and morphology of the



Rolling motion in erupting prominences observed by STEREO

Stereoscopic Analysis of the 31 August 2007 Prominence Eruption and Coronal Mass Ejection

The spectacular prominence eruption and CME of 31 August 2007 are analyzed stereoscopically using data from NASA’s twin Solar Terrestrial Relations Observatory (STEREO) spacecraft. The technique of

3D Reconstruction of a Rotating Erupting Prominence

A bright prominence associated with a coronal mass ejection (CME) was seen erupting from the Sun on 9 April 2008. This prominence was tracked by both the Solar Terrestrial Relations Observatory

Formation, Interaction and Merger of an Active Region and a Quiescent Filament Prior to Their Eruption on 19 May 2007

We report observations of the formation of two filaments – one active and one quiescent, and their subsequent interactions prior to eruption. The active region filament appeared on 17 May 2007,


On 2009 September 21, a filament eruption and the associated coronal mass ejection (CME) were observed by the Solar Terrestrial Relations Observatory (STEREO) spacecraft. The CME originated from the


Two well known phenomena associated with erupting filaments are the transient coronal holes that form on each side of the filament channel and the bright post-event arcade with its expanding double

Stereoscopic Analysis of the 19 May 2007 Erupting Filament

A filament eruption, accompanied by a B9.5 flare, coronal dimming, and an EUV wave, was observed by the Solar TERrestrial Relations Observatory (STEREO) on 19 May 2007, beginning at about 13:00 UT.

On the Formation of Filament Channels

From the Hα archive of the Big Bear Solar Observatory (BBSO) we have selected three examples showing fibril structures that change their orientation, over 1 or 2 days, from nearly perpendicular to

Non-radial motion of eruptive filaments

We develop a simple model to explain the non-radial motion of eruptive solar filaments under solar minimum conditions. The global magnetic field is derived from the first and third components of the

The link between CMEs, filaments and filament channels

We present a broad concept for the build-up to eruptive solar events which needs to be tested in future observational and theoretical research. In this concept an eruptive solar event consists of a
