Features of Ground Level Enhancement (GLE #74) Event on 11 May 2024

Journal of Geophysical Research: Space Physics, Volume 131, Issue 10, October 2026.
Abstract Ground Level Enhancement (GLE #74) occurred on 11 May 2024 following an X5.8 solar flare from active region AR 13668 and the associated halo coronal mass ejection. The event was observed by both ground‐based neutron monitors (NMs) and space‐borne instruments and occurred during a deep Forbush decrease and one of the strongest geomagnetic ...

Faint Diffuse 557.7‐nm Emissions Equatorward of the Auroral Oval: Conjugate Observations by Ground Airglow Imagers and the Arase Satellite

Journal of Geophysical Research: Space Physics, Volume 131, Issue 10, October 2026.
Abstract At subauroral latitudes, discrete auroras, such as strong thermal emission velocity enhancement and stable auroral red arcs, have been extensively studied. On the other hand, diffuse emissions at subauroral latitudes have not been studied well.

Effects of Microgravity on Muscle and Bone Health in Astronauts During Space Missions: Preventive Procedures and Medical Interventions

Hanggong uju uihakoeji
This study examines the effects of microgravity and space radiation on astronauts’ muscle and bone health during space missions. Microgravity leads to muscle atrophy and alterations in muscle tissue composition, whereas space radiation impacts bone ...

Cross‐Referencing Astronaut‐Observed Lunar Impact Flashes With Seismic Data—Lessons From Apollo for Artemis

Journal of Geophysical Research: Planets, Volume 131, Issue 10, October 2026.
Abstract During their orbits of the Moon in 1972, Apollo astronauts reported three impact flashes, associated with meteoroids striking the surface and vaporizing. We examined data from the Apollo seismic network to investigate whether these flashes produced detectable moonquakes whose locations and timing could be independently validated.

Ancient Impact Melt Near the Lunar South Pole: Distribution, Provenance, and Sampling Strategy

Journal of Geophysical Research: Planets, Volume 131, Issue 10, October 2026.
Abstract Due to a lack of pre‐Nectarian samples associated with specific impacts in the Apollo suite, the early Solar System's impact chronology is poorly constrained. We investigate where Artemis and other south polar lunar missions could sample impactites to determine the ages of pre‐Nectarian craters, focusing on the ancient craters Haworth ...

Sea Surface Conditions and Antarctic Bottom Water Formation Offshore Cape Darnley, East Antarctica, Over the Last 600 ka: New Insights From the Diatom Record

Paleoceanography and Paleoclimatology, Volume 41, Issue 10, October 2026.
Abstract The Cape Darnley marine region of East Antarctica is one of only four sectors where Antarctic Bottom Water (AABW) is produced. AABW formation at Cape Darnley is highly dependent on surface ocean processes—specifically, the high production of frazil ice. Here, we investigated the sea surface conditions at Cape Darnley over the past 600 thousand
