A solar storm observed from the Sun to Venus using the STEREO, Venus Express, and MESSENGER spacecraft [PDF]

open access: yes, 2009
The suite of SECCHI optical imaging instruments on the STEREO-A spacecraft is used to track a solar storm, consisting of several coronal mass ejections (CMEs) and other coronal loops, as it propagates from the Sun into the heliosphere during May 2007 ...

Simultaneous interplanetary scintillation and Heliospheric Imager observations of a coronal mass ejection [PDF]

open access: yes, 2008
We describe simultaneous Interplanetary Scintillation (IPS) and STEREO Heliospheric Imager (HI) observations of a coronal mass ejection (CME) on 16 May 2007. Strong CME signatures were present throughout the IPS observation.

Understanding the Origins of Problem Geomagnetic Storms Associated with "Stealth" Coronal Mass Ejections. [PDF]

open access: yesSpace Sci Rev, 2021
Geomagnetic storms are an important aspect of space weather and can result in significant impacts on space- and ground-based assets. The majority of strong storms are associated with the passage of interplanetary coronal mass ejections (ICMEs) in the ...

From the Sun to the Earth: The 13 May 2005 Coronal Mass Ejection [PDF]

open access: yes, 2010
We report the results of a multi-instrument, multi-technique, coordinated study of the solar eruptive event of 13 May 2005. We discuss the resultant Earth-directed (halo) coronal mass ejection (CME), and the effects on the terrestrial space environment ...

Propagation of Coronal Mass Ejections from the Sun to Earth

open access: yes, 2022
Coronal Mass Ejections (CMEs), as they can inject a large amounts of mass and magnetic flux into the interplanetary space, are the primary source of space weather phenomena on the Earth.

Very narrow coronal mass ejections producing solar energetic particles [PDF]

open access: yes, 2018
Aims. Our main aim is to study the relationship between low-energy solar particles (energies below 1 MeV) and very narrow coronal mass ejections (jets with angular width 20). Methods.

Height‐Dependent Evolution of the Ionospheric Response to the May 2024 Superstorm: Global GNSS‐POD, GNSS‐RO, and Ground‐Based Observations

open access: yesJournal of Geophysical Research: Space Physics, Volume 131, Issue 6, June 2026.
Abstract Capturing global ionospheric response during extreme geomagnetic storms remains a major observational challenge. During 10–11 May, 2024 superstorm, we investigate the height‐dependent response of the F‐region using multi‐constellation GNSS‐POD limb‐sounding measurements from COSMIC‐2, Spire, PlanetiQ, and FengYun‐3 satellites. Approximately 12,

Predicting Nitrogen Isotope Fractionation in Nitrate Deposition on Early Mars

open access: yesJournal of Geophysical Research: Planets, Volume 131, Issue 6, June 2026.
Abstract Noachian and early Hesperian Mars were likely warm and wet, with an atmosphere abundant in molecular nitrogen. The recent discovery of nitrate deposits in the Yellowknife Bay mudstones at Gale Crater confirm the existence of nitrogen oxides (NOX) on Noachian Mars. The processes responsible for the production of these nitrates would fractionate

Coronal Mass Ejections

open access: yes, 2006
It is well known that the Sun gravitationally controls the orbits of planets and minor bodies. Much less known, however, is the domain of plasma fields and charged particles in which the Sun governs a heliosphere out to a distance of about 15 billion ...

Comparing Solar Structure Detection Methods in SDO/AIA Observations and the Application to Raw Uncalibrated Data

open access: yesJournal of Geophysical Research: Machine Learning and Computation, Volume 3, Issue 3, June 2026.
Abstract Recent advances in solar physics increasingly rely on automated identification of coronal structures using machine learning. Yet most studies emphasize scientific performance without evaluating feasibility for onboard deployment to prioritize downlink observations.
