Spatial Relationship between CMEs and Prominence Eruptions during SC 24 and SC 25

open access: yesThe Astrophysical Journal
During their propagation, coronal mass ejections (CMEs) and prominences sometimes display a nonradial motion. During the years after the solar minimum, the CME central position angle tended to be offset closer to the equator compared to that of the ...

Characteristics of coronal mass ejections in the near Sun interplanetary space [PDF]

open access: yesGeofísica Internacional, 2004
Based on the observations from the Large Angle and Spectrometric Coronagraph (LASCO) on board the Solar and Heliospheric Observatory (SOHO) spacecraft we studied coronal mass ejections (CME) parameters between 6 and 10 solar radii from the Sun.

On flare-CME characteristics from Sun to Earth combining remote-sensing image data with in-situ measurements supported by modeling

open access: yes, 2017
We analyze the well observed flare-CME event from October 1, 2011 (SOL2011-10-01T09:18) covering the complete chain of action - from Sun to Earth - for a better understanding of the dynamic evolution of the CME and its embedded magnetic field.

Direct Evidence of the Hybrid Nature of Extreme-ultraviolet Waves and the Reflection of the Fast-mode Wave

open access: yesThe Astrophysical Journal
We performed an analysis of the extreme-ultraviolet (EUV) wave event on 2022 March 31. The event originated from active region (AR) 12975 located at N13W52 in the field of view of the Atmospheric imaging Assembly (AIA) and exactly at the west limb viewed

Two classes of solar energetic particle events associated with impulsive and long duration soft X-ray flares [PDF]

open access: yes
Solar energetic particle events observed in space have different properties depending on the class of associated flare. Impulsive flares, which occur low in the corona in regions of high energy density, are associated with particle events which are ...

Can solar wind viscous drag account for CME deceleration?

open access: yes, 2012
The forces acting on solar Coronal Mass Ejections (CMEs) in the interplanetary medium have been evaluated so far in terms of an empirical drag coefficient $C_{\rm D} \sim 1$ that quantifies the role of the aerodynamic drag experienced by a typical CME ...

Transport in the interplanetary medium of coronal mass ejections [PDF]

open access: yesGeofísica Internacional, 2008
Coronal mass ejections (CMEs) are large scale structures of plasma and magnetic field expelled from the Sun to the interplanetary medium and generally observed in white light coronagraphs.

Probabilistic forecasting of ionospheric scintillation and GNSS receiver signal tracking performance at high latitudes

open access: yesAnnals of Geophysics, 2013
At high latitudes, phase scintillation occurs predominantly on the dayside in the ionospheric footprint of the magnetospheric cusp, and in the nightside auroral oval. A new technique of probabilistic forecasting of phase scintillation occurrence relative
