COMPARATIVE ANALYSIS OF GEOMAGNETIC DISTURBANCES IN THE ODESSA MAGNETIC ANOMALY AREA IN THE 24TH SOLAR ACTIVITY CYCLE

Radio Physics and Radio Astronomy, 2019
Purpose: The main oscillation periods of the geomagnetic field perturbation level in the Odesa magnetic anomaly area are studied by the data observed at the “Odesa” geomagnetic observatory within the 24th solar activity cycle.

Persistence and Dynamics of an Sq‐like Mid‐Latitude Current Vortex During the May 2024 Superstorm

Geophysical Research Letters, Volume 53, Issue 21, 16 November 2026.
Abstract The solar quiet (Sq) current system describes the mid‐latitude equivalent current under quiet geomagnetic conditions, but whether an Sq‐like vortex persists during intense storms remains unclear. Using dense East Asian magnetometer observations, including the Chinese Meridian Project, we reconstruct the storm‐time ionospheric equivalent ...

Intense Magnetopause Erosion at Earth During the May 2024 Solar Storm

Geophysical Research Letters, Volume 53, Issue 21, 16 November 2026.
Abstract Earth's main magnetic field forms the magnetosphere, shielding the planet from solar wind plasma. Southward interplanetary magnetic fields erode the magnetosphere, a process known as magnetopause erosion, allowing solar wind penetration close to the Earth.

White light reduces flight height of birds in low‐density migration corridor

The Journal of Wildlife Management, Volume 90, Issue 8, November 2026.
We conducted an experiment to better understand the effects of artificial light at night treatments of varying spectral power distributions on in‐flight migratory bird behavior as measured by a portable radar. Broad‐spectrum white light emissions reduced avian flight height as compared to dark periods and more than other light treatments.

Influence of geomagnetic activity on mesopause temperature over Yakutia [PDF]

Atmospheric Chemistry and Physics, 2018
The long-term temperature changes of the mesopause region at the hydroxyl molecule OH (6-2) nighttime height and its connection with the geomagnetic activity during the 23rd and beginning of the 24th solar cycles are presented.

Empirical Parameterizations of ULF Power and Drift Orbit Averaged Radial Diffusion Coefficients From Ground Magnetometers for Different MLT

Earth and Space Science, Volume 13, Issue 11, November 2026.
Abstract Radial diffusion, driven by ultra‐low frequency (ULF) waves, is an important process for the transport of electrons in the outer radiation belt. Ground magnetometers give us constant observations of such ULF waves but their usefulness is limited by the models used to transform ground measurements into their progenitor fields in space.

PROSWIN: Probabilistic Solar Wind Speed Forecasting Using Deep Distributional Regression From Solar Images

AGU Advances, Volume 7, Issue 8, November 2026.
Abstract Accurately predicting fast solar wind conditions is challenging, as uncertainties are large and unquantified by traditional single‐value prediction models. In particular, the risks of high‐speed solar wind streams (HSSs), which can cause damage to technological infrastructure, cannot be reliably assessed without probabilistic forecasts.

From Fault Ruptures to Atmospheric Perturbations: Examining the 2016 Norcia Seismic Sequence

Earth and Space Science, Volume 13, Issue 11, November 2026.
Abstract This study investigates lithosphere–atmosphere interactions during the 2016 Central Italy seismic sequence, providing the first systematic analysis of atmospheric impacts across the entire series within a complex tectonic setting. The static displacement fields of the main events were modeled using the Okada formulation and validated against ...
