Identifying and Predicting Coronal Mass Ejection Occurrence: Observational Checklists for Space Weather Forecasters

Space Weather, Volume 24, Issue 6, June 2026.
Abstract Ejections of magnetized plasma from the Sun, known as coronal mass ejections, can drive major geomagnetic activity if Earth‐directed, and are therefore monitored by space weather forecasters. The current focus being the forecast of the arrival time of a coronal mass ejection at Earth and the level of geomagnetic impact.

Observational Evidence of the Kink Instability in Solar Filament Eruptions and Sigmoids [PDF]

The Astrophysical Journal, 2005
Two lines of observational evidence are used to infer that the MHD helical kink instability is associated with solar eruptions. The senses of twist and writhe are determined in images of seven erupting filaments obtained at 10830, 1600, 195, and 171 ?. In every case the sense of twist is the same as the sense of writhe, as required for a kink.

Advancing Heliophysics and Space Weather Modeling Through Open Science

Space Weather, Volume 24, Issue 6, June 2026.
Abstract We present a community‐wide effort to develop a strategy and action plan to advance heliophysics and space weather modeling through open science. While open science has the potential to enhance the quality and pace of scientific discovery, its application to scientific modeling requires more careful consideration regarding open data and open ...

Critical Decay Index in the Rectangular Circuit Model of an Eruptive Prominence

The Astrophysical Journal
Torus instability is currently considered the most likely mechanism for the sudden onset of the rapid rise of magnetic flux ropes observed on the Sun as prominence eruptions and coronal mass ejections.

The Life Cycle of a Stratospheric Smoke Plume as Seen From EarthCARE—Tracking a Plume From Canada to Europe

Geophysical Research Letters, Volume 53, Issue 7, 16 April 2026.
Abstract At the end of May 2025, extremely strong wildfires in Canada produced several pyrocumulonimbus clouds lifting the smoke particles up to the lower stratosphere. Stratospheric aerosol optical depths of more than 2.5 were observed by the ATmospheric LiDAR (ATLID) onboard of the Earth Cloud, Aerosol and Radiation Explorer (EarthCARE) satellite ...

Photospheric Horizontal Magnetic Field Decrease Preceding a Major Solar Eruption

The Astrophysical Journal
Significant photospheric magnetic field changes during major solar eruptions—interpreted as coronal feedback from eruptions to the photosphere—are well-observed. However, analogous short-timescale field changes preceding eruptions are rarely reported. In

The Microbiology and Geochemistry of the Shallow‐Water Hydrothermal Vents of the Gulf of Naples, Italy

Environmental Microbiology, Volume 28, Issue 4, April 2026.
This study investigated the interplay between fluid geochemistry and microbial diversity in the shallow‐water hydrothermal vents of the gulf of Naples, Italy. We found that hydrothermal fluid chemistry and the geological settings where the vents are hosted play a key role in shaping microbial distribution.

The Cycles and Dynamical Properties of Convective Outbreaks in Jupiter's Highest Speed Jet From a 55‐Year Study

Geophysical Research Letters, Volume 53, Issue 3, 16 February 2026.
Abstract Jupiter's most intense jet at planetographic latitude 23.7°N experiences vigorous planetary‐scale disturbances. The onset consists of the outbreak of 1–3 bright clouds of convective origin developing turbulent plumes. Observed events between 1970 and 2025 shows a cycle of activity with a period in the range of 3.8–5.1 yrs interrupted between ...
