The Hermean Helium Exosphere—Continuous and Sporadic Helium Release Processes

Journal of Geophysical Research: Planets, Volume 130, Issue 4, April 2025.
Abstract Since its detection by Mariner 10, helium has been a key focus in studies of Mercury's exosphere. Recently, Weichbold et al. (2025), https://doi.org/10.1029/2024je008679 provided the first in situ helium measurements, inferring density from Ion Cyclotron Wave (ICW) events observed by the MESSENGER spacecraft.

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

The 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.

Data‐Driven Transfer Functions From Differential Magnetometer Measurements to Enhance GIC Model Validation Capability: A Case Study in the Spanish Power Grid

Space Weather, Volume 23, Issue 4, April 2025.
Abstract Geomagnetically induced currents (GICs) are unwanted currents flowing in long grounded conductors because of space weather phenomena. Example GICs are those flowing in power transmission lines via grounded transformer neutrals. Prediction models, used to foresee the amplitudes and waveforms of those currents and to identify weak points in ...

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

Journal 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 ...

The Magnetosphere‐Ionosphere‐Ground Responses to the May 2024 Super Solar Storm

Space Weather, Volume 23, Issue 4, April 2025.
Abstract Earth suffered the attack of the strongest geomagnetic storm in the last 20 years (Kp = 9, Dst∼ ${\sim} $ −400 nT) occurred on 11 May 2024. Taking advantage of the LEO multi‐parameter CSES satellite (launched in 2018) with a large inclination angle 97° $97{}^{\circ}$, with the joint observations of NOAA and GOES, we present a comprehensive ...

The interplanetary mass ejections behaviour in the heliosphere [PDF]

Romanian Journal of Physics, 58, 3-4, p.383-394, 2013, 2014
We present here an overview of an important solar phenomenon with major implication for space weather and planetary life. The coronal mass ejections (CMEs) come from the Sun and expand in the heliosphere, becoming interplanetary coronal mass ejections (ICMEs). They represent huge clouds of plasma and magnetic fields that travel with velocities reaching

Unveiling Ionospheric Response to the May 2024 Superstorm With Low‐Earth‐Orbit Satellite Observations

Space Weather, Volume 23, Issue 4, April 2025.
Abstract The space weather event on 10–11 May 2024 was a high‐impact geomagnetic storm, resulting in a SYM‐H index decrease to −518 nT, the lowest level registered in several decades. We investigated the response of the Earth's ionosphere during the main phase of this storm using a comprehensive data set of ionospheric observations (in situ plasma ...

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

The 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 ...
