Magnetopause Boundary Layers in Low Mach CME‐Driven Storm Environment

Geophysical Research Letters, Volume 53, Issue 8, 28 April 2026.
Abstract Magnetopause boundary layers (BLs) play an important role mediating plasma and energy exchange between the solar wind/magnetosheath and Earth's magnetosphere. Energy exchange across the magnetopause is enhanced during storms, yet little work has been done investigating BLs during storms.

Probing Velocity Dispersion Inside Coronal Mass Ejections: New Insights on Their Initiation

The Astrophysical Journal Letters
This work studies the kinematics of the leading edge and the core of six coronal mass ejections (CMEs) in the combined field of view of Sun Watcher using Active Pixel System detector and Image Processing (SWAP) on board PRoject for On-Board Autonomy ...

Solar Transients disturbing the Terrestrial Magnetic Environment at Higher Latitudes

, 2013
Geomagnetic field variations during five major Solar Energetic Particle (SEP) events of solar cycle 23 have been investigated in the present study. The SEP events of 01 oct 2001, 04 Nov 2001, 21 Apr 2002 and 14 May 2005 have been selected to study the ...

Different triggering mechanisms for solar flares and coronal mass ejections [PDF]

Astronomy & Astrophysics, 2008
Context. Experimental observations indicate that flares and CMEs are often associated, even if the precise relationship between the two phenomena is a still hot and open question. Aims. We present a study of the statistical properties of solar flare and CME temporal organisation, in order to enlighten differences in the mechanisms at the basis of their

A Physics‐Informed Neural Network Approach to the Gannon Storm

Geophysical Research Letters, Volume 53, Issue 7, 16 April 2026.
Abstract Extreme geomagnetic storms, such as the May 2024 Gannon event, pose significant risks to technological infrastructure, requiring robust forecasting models. Here, we apply Physics‐Informed Neural Networks (PINNs) to the Burton equation to model the storm's ring current dynamics by studying the temporal evolution of the SuperMAG SMR index during

Causal Relationships between Eruptive Prominences and Coronal Mass Ejections [PDF]

, 2007
A close association between eruptive prominences and CMEs, both slow and fast CMEs, was reported in many studies. Sometimes it is possible to follow the material motion starting from the prominence (filament) activation to the CME in the high corona ...

SOLAR WIND DRAG AND THE KINEMATICS OF INTERPLANETARY CORONAL MASS EJECTIONS [PDF]

The Astrophysical Journal, 2010
Coronal mass ejections (CMEs) are large-scale ejections of plasma and magnetic field from the solar corona, which propagate through interplanetary space at velocities of $\sim$100--2500~km~s$^{-1}$. Although plane-of-sky coronagraph measurements have provided some insight into their kinematics near the Sun ($

Automated Detection of Coronal Mass Ejections with Few-shot Learning

The Astrophysical Journal Supplement Series
Coronal mass ejections (CMEs) are a primary driver of severe space weather impacts, yet accurate delineation of CME structure in coronagraph images remains challenging.

Coronal Loop Detection Using Multiscale Convolutional Neural Networks

The Astrophysical Journal Supplement Series, 2023
Solar magnetic fields play an important role in many solar activities, such as the solar wind, coronal mass ejections, and coronal oscillation. Coronal loops are curvilinear structures in the solar atmosphere and are closely related to coronal magnetic ...
