A Comparison of Modeled and Observed Dayside Bow Shock Locations in 8 Years of MMS Data
Journal of Geophysical Research: Space Physics, Volume 130, Issue 11, November 2025.Abstract The interplay between Earth's magnetic field and the solar wind provides a natural laboratory to study the physics of shock waves in collisionless plasmas. 3D parameterized shape models of Earth's bow shock boundary quantify how this interaction depends on upstream solar wind parameters.

Journal of Geophysical Research: Space Physics, Volume 130, Issue 11, November 2025.Abstract We present observations of a rare configuration of Mercury's magnetosphere in response to sub‐Alfvénic upstream conditions, driven by an interplanetary coronal mass ejection (ICME) that impacted the planet on 1 May 2013. Using data from the Mercury Surface, Space Environment, Geochemistry, and Ranging (MESSENGER) spacecraft, supported by a ...

Felsic Magmatism on Venus Generated by Crustal Recycling and Melting
Journal of Geophysical Research: Planets, Volume 130, Issue 11, November 2025.Abstract The observation of low viscosity lava flows and shield volcanoes on radar images, combined with X‐ray fluorescence analyses performed by Soviet landers, strongly suggests that Venus's crust is primarily basaltic. However, near‐infrared emissivity data from the Galileo and Venus Express missions indicate that crustal plateaus may be ...

Forward and inverse three-dimensional P wave velocity models of the southern California crust [PDF]
, 1992 We construct a three-dimensional P wave velocity model of the southern California crust by combining existing one-dimensional models, each describing a region defined by surface geology, and calibrate the model with travel times from three explosions ...

Monitoring the Solar Wind Before It Reaches L1
Space Weather, Volume 23, Issue 11, November 2025.Abstract Space weather predictions of the solar wind impacting Earth are usually first based on remote‐sensing observations of the solar disc and corona, and eventually validated and/or refined with in situ measurements taken at the Sun–Earth Lagrange L1 point, where real‐time monitoring probes are located.

Microwave scattering and emission properties of large impact craters on the surface of Venus [PDF]
Many of the impact craters on Venus imaged by the Magellan synthetic aperture radar (SAR) have interior floors with oblique incidence angle backscatter cross sections 2 to 16 times (3 dB to 12 dB) greater than the average scattering properties of the ...

Space Weather, Volume 23, Issue 11, November 2025.Abstract A new daily composite of the solar flare index (SFI) and the hemispherically‐resolved versions (hSFI) are presented for 1937 to 2024. The data set confirms that the northern hemisphere (NH) dominated solar flare activity during Solar Cycles 17 to 21, but that the southern hemisphere has dominated from Solar Cycle 22 to present.

Magellan stereo images and Venusian geology [PDF]
Areas of Venus imaged by Magellan radar with multiple viewing conditions provide unique data that will contribute to the solution of venusian geologic problems and provide a basis for quantitative comparison of venusian landforms with those on other ...

Modelling fire occurrence at regional scale. Does vegetation phenology matter? [PDF]
, 2015 Through its influence on biomass production, climate controls fuel availability affecting at the same time fuel moisture and flammability, which are the main determinants for fire ignition and propagation.
