Forecasting Coronal Mass Ejections Using Transformers: A Comparative Study of Flare‐Associated Versus Flare‐Independent Approaches

open access: yesSpace Weather, Volume 23, Issue 8, August 2025.
Abstract Forecasting coronal mass ejections (CMEs) remains a challenge, and no reliable, accurate forecasting method has yet been developed. Knowing that CMEs can occur in association with flares, we compare two approaches: (a) forecasting CMEs by coupling to flare forecasting, and (b) forecasting CMEs independently of flare occurrence.

Identifying Coronal Mass Ejection Active Region Sources: An Automated Approach

open access: yesThe Astrophysical Journal
Identifying the source regions of coronal mass ejections (CMEs) is crucial for understanding their origins and improving space weather forecasting. We present an automated algorithm for matching CMEs detected by the Large Angle Spectrometric Coronagraph ...

Modular Femoral Stem for Hartofilakidis Type C Hip Dysplasia: Is It Necessary for 1‐mm Increment of Distal Stem Diameter?

open access: yesOrthopaedic Surgery, Volume 17, Issue 8, Page 2313-2320, August 2025.
Modular femoral stem with a skipping size caused serious complications such as distal femoral fractures in Chinese high‐riding DDH patients. A 1 mm increment of the femoral stem is necessary. ABSTRACT Background S‐ROM prosthesis, one well‐used femoral prosthesis in the patients with developmental dysplasia of the hip (DDH), has a skipping size of the ...

Acceleration and Release of Solar Energetic Particles Associated with a Coronal Shock on 2021 September 28 Observed by Four Spacecraft

open access: yesThe Astrophysical Journal
The main driver of the acceleration of solar energetic particles (SEPs) is believed to be shocks driven by coronal mass ejections. Extreme-ultraviolet (EUV) waves are thought to be the propagating footprint of the shock on the solar surface.

Multi-instrument observations and tracking of a coronal mass ejection front from low to middle corona

open access: yesJournal of Space Weather and Space Climate
The shape and dynamics of coronal mass ejections (CMEs) vary significantly based on the instrument and wavelength used. This has led to significant debate about the proper definitions of CME/shock fronts, pile-up/compression regions, and core ...

Slow Solar Wind: Origin in an Independent Small‐Scale Solar Dynamo

open access: yesGeophysical Research Letters, Volume 52, Issue 13, 16 July 2025.
Abstract Separation of the solar wind (SW) into three flow types (coronal mass ejections (CMEs), high speed streams (HSSs), and slow solar wind (SSW)) reveals an inverse relationship between the percentage of time Earth spends in SSW during a year and its annually averaged magnetic field strength (B).

Solar Mass Ejections and Coronal Holes [PDF]

open access: yesInternational Astronomical Union Colloquium, 1996
AbstractIn this paper we present observations of two types of solar mass ejections, which seem to be associated with the location of coronal holes. In the first type, a filament eruption was observed near a coronal hole, which gave rise to a strong interplanetary scintillations, as detected by IPS observations.

Interaction between a Coronal Mass Ejection and Comet 67P/Churyumov–Gerasimenko

open access: yesThe Astrophysical Journal
The interaction between a coronal mass ejection (CME) and a comet has been observed several times by in situ observations from the Rosetta Plasma Consortium, which is designed to investigate the cometary magnetosphere of comet 67P/Churyumov–Gerasimenko ...
