A review of the SCOSTEP’s 5-year scientific program VarSITI—Variability of the Sun and Its Terrestrial Impact

Progress in Earth and Planetary Science, 2021
The Sun is a variable active-dynamo star, emitting radiation in all wavelengths and solar-wind plasma to the interplanetary space. The Earth is immersed in this radiation and solar wind, showing various responses in geospace and atmosphere.

Investigating Potential Benefits of Future Sub‐L1 Missions With STEREO‐A

Space Weather, Volume 24, Issue 6, June 2026.
Abstract We present the first statistical study of geomagnetic storm forecasting using in situ data from the STEREO‐A spacecraft as a sub‐L1 monitor. Between November 2022 and June 2024, STEREO‐A crossed the Sun–Earth line, covering longitudinal and radial separations of ±15° $\pm 15{}^{\circ}$ from the Sun–Earth line and 0.01–0.06 au from Earth.

Regional and Seasonal Effects of Geomagnetic Storms on Terrestrial Weather

Geophysical Research Letters, Volume 53, Issue 10, 28 May 2026.
Abstract It has long been a mystery why small Total Solar Irradiation changes have significant effects on Earth's climate. Solar cycle correlation studies abound but cannot conclusively point to a viable physical mechanism. Here, I show that geomagnetic storms have a profound terrestrial weather impact.

Sun Radio Interferometer Space Experiment (SunRISE): Tracking Particle Acceleration and Transport in the Inner Heliosphere

, 2017
The authors present a space-based array designed to localize and track the radio emission associated with coronal mass ejections (CMEs) from the Sun. Radio emission from CMEs is a direct tracer of the particle acceleration in the inner heliosphere and ...

Voyager 2 observation of the multifractal spectrum in the heliosphere and the heliosheath [PDF]

Nonlinear Processes in Geophysics, 2013
We look in detail at the multifractal scaling of the fluctuations in the interplanetary magnetic field strength as measured onboard Voyager 2 in the entire heliosphere and even in the heliosheath.

The 3-D Sun and heliosphere at solar maximum [PDF]

Astronomy and Geophysics, 2002
Bob Forsyth and Andy Breen report from the RAS G Discussion Meeting at the Geological Society on 11 January 2002. Presentations came from both the solar and heliospheric communities, on the 3-D structure and dynamics of the solar corona and heliosphere and their inter-relation during the present maximum in the solar activity cycle.

Soft X‐Ray Emission From Saturn's Magnetosheath II: Solar Wind Driving

Journal of Geophysical Research: Space Physics, Volume 131, Issue 5, May 2026.
Abstract Saturn's magnetosphere is dominated by Enceladus‐sourced neutrals, which spread throughout the system into the magnetosheath. The neutrals can charge exchange with highly charged solar wind ions, causing soft X‐ray emission (<2 ${< } 2$ keV) upon de‐excitation of the ion.

ICMEs in the inner heliosphere: origin, evolution and propagation effects

, 2006
This report assesses the current status of research relating the origin at the Sun, the evolution through the inner heliosphere and the effects on the inner heliosphere of the interplanetary counterparts of coronal mass ejections (ICMEs).

First Imaging of Coronal Mass Ejections in the Heliosphere Viewed from Outside the Sun Earth Line [PDF]

, 2007
peer reviewedWe show for the first time images of solar coronal mass ejections (CMEs) viewed using the Heliospheric Imager (HI) instrument aboard the NASA STEREO spacecraft. The HI instruments are wide-angle imaging systems designed to detect CMEs in the
