Probing Coronal Mass Ejection Inclination Effects with EUHFORIA
The Astrophysical JournalCoronal mass ejections (CMEs) are complex magnetized plasma structures in which the magnetic field spirals around a central axis, forming what is known as a flux rope (FR).

FORECASTING A CORONAL MASS EJECTION'S ALTERED TRAJECTORY: ForeCAT [PDF]
, 2013 To predict whether a coronal mass ejection (CME) will impact Earth, the effects of the background on the CME's trajectory must be taken into account. We develop a model, ForeCAT (Forecasting a CME's Altered Trajectory), of CME deflection due to magnetic ...

Gradual Solar Coronal Dimming and Evolution of Coronal Mass Ejection in the Early Phase
, 2017 We report observations of a two-stage coronal dimming in an eruptive event of a two-ribbon flare and a fast coronal mass ejection (CME). Weak gradual dimming persists for more than half an hour before the onset of the two-ribbon flare and the fast rise ...

Upper Atmospheric Vortices Following Strong Geomagnetic Storms
Geophysical Research Letters, Volume 52, Issue 11, 16 June 2025.Abstract This paper presents observations of upper atmospheric vortices following two geomagnetic storms: a Kp 9− storm on 10 October 2024 and a Kp 8+ storm occurring in April of 2023. These observations, using neutral composition and effective neutral temperatures from the NASA GOLD mission, reveal vortices similar to those initially reported by Evans,

The Astrophysical JournalCoronal mass ejections (CME) are regarded as the main drivers of geomagnetic storms (GSs). In the prediction of geoeffectiveness, various CME features have been introduced without adequately considering the geoeffectiveness of CMEs and strong ...

A Type II Radio Burst Driven by a Blowout Jet on the Sun
The Astrophysical Journal, 2023 Type II radio bursts are often associated with coronal shocks that are typically driven by coronal mass ejections (CMEs) from the Sun. Here we conduct a case study of a type II radio burst that is associated with a C4.5-class flare and a blowout jet, but

Kinematical properties of coronal mass ejections [PDF]
Astronomische Nachrichten, 2016 AbstractCoronal mass ejections (CMEs) are the most dynamic phenomena in our solar system. They abruptly disrupt the continuous outflow of solar wind by expelling huge clouds of magnetized plasma into interplanetary space with velocities enabling to cross the Sun‐Earth distance within a few days.

Fetal Cardiovascular Magnetic Resonance: History, Current Status, and Future Directions
Journal of Magnetic Resonance Imaging, Volume 61, Issue 6, Page 2357-2375, June 2025.Fetal cardiovascular magnetic resonance imaging (MRI) has emerged as a complementary modality for prenatal imaging in suspected congenital heart disease. Ongoing technical improvements extend the potential clinical value of fetal cardiovascular MRI.

Dynamic disappearance of prominences and their geoeffectiveness [PDF]
Geofísica Internacional, 2008 We study 14 cases of dynamic “disparition brusque” (DBd), the sudden disappearance of quiescent filaments/prominences, during two solar minima: 1985-1986 and 1994.

SITCoM: SiRGraF Integrated Tool for Coronal dynaMics
Frontiers in Astronomy and Space Sciences, 2023 SiRGraF Integrated Tool for Coronal dynaMics (SITCoM) is based on the Simple Radial Gradient Filter used to filter the radial gradient in the white-light coronagraph images and bring out dynamic structures.
