A Solar Analog Model for Decrease in Far Ultraviolet Irradiance Under a Grand Minimum

Earth and Space Science, Volume 13, Issue 9, September 2026.
Abstract Solar analog field stars having a range of magnetic activity can provide an estimate of solar spectral irradiance (SSI) variability relevant to understanding the Sun's influence on terrestrial climate. This approach is particularly useful for far ultraviolet (FUV) irradiance that cannot be observed from the Earth surface.

On the Effects of the Solar Wind Structure in the Global Distribution of dBH/dt ${\text{dB}}_{H}/\text{dt}$ Spikes During Geomagnetic Storms

Journal of Geophysical Research: Space Physics, Volume 131, Issue 9, September 2026.
Abstract Variations in the solar wind, particularly those associated with interplanetary coronal mass ejections (ICMEs) and high‐speed streams (HSSs), drive geomagnetic disturbances that produce rapid changes in the ground magnetic field. These variations, commonly quantified by the time derivative of the horizontal magnetic field dBH/dt $\left({\text ...

Statistical Scale Analyses of a Diurnal Periodicity in Auroral Kilometric Radiation, Observed by Wind/WAVES

Journal of Geophysical Research: Space Physics, Volume 131, Issue 9, September 2026.
Abstract The Earth's strongest natural radio emission is Auroral Kilometric Radiation (AKR), which is correlated with auroral intensity, and is a barometer for space weather. AKR is generated by the electron cyclotron maser instability, with sources on auroral field lines. Previous work on AKR and radio emissions from other planets (or stars) points to

Iono‐PhyTAU: A Lightweight Global Ionospheric TEC Prediction Model Based on Temporal Attention Unit and Physical Condition Constraints of the Ionosphere

Space Weather, Volume 24, Issue 9, September 2026.
Abstract Ionospheric Total Electron Content (TEC) is the primary error source causing signal delay in Global Navigation Satellite Systems (GNSS). High‐precision TEC prediction is essential for positioning, navigation, and space weather monitoring. Although deep learning models including ConvLSTM, ConvGRU, and Transformer have advanced TEC forecasting ...

Risk factors for the development of subretinal fluid in the fellow eyes of patients with chronic central serous chorioretinopathy

Acta Ophthalmologica, Volume 104, Issue 6, Page 666-673, September 2026.
Abstract Purpose To assess the risk of subretinal fluid (SRF) development in the fellow eye of chronic central serous chorioretinopathy (cCSC) patients with unilateral SRF at baseline. Methods Medical records of 334 presumed cCSC patients were retrospectively reviewed.
