Optimization Algorithms for Retrieving the Bottomside Ionospheric B0 and B1 Parameters

Radio Science, Volume 61, Issue 10, October 2026.
Abstract The bottomside morphological parameters of the ionospheric F2 layer, the thickness parameter B0 and the shape parameter B1, are crucial for describing electron density profiles and monitoring space weather. However, existing climatological models and indirect ionosonde approaches have limitations in real‐time applicability and direct ...

Sunspot numbers in telescopic era

, 2019
Abstract. This is a literature review about the solar cycle and its variations, with a focus on sunspots. We also make a review of the different types of sunspot numbers currently in use and a comparison between their respective advantages and disadvantages, primarily focusing in their extension to the period between 1600 and 1900 AD.Aurinkopilkkujen ...

Integrated Digital Garment Modeling and Monte Carlo Simulation of a Water‐Based Radiation Protection Vest for Spaceflight Radiation Hazards

Space Weather, Volume 24, Issue 10, October 2026.
Abstract As crewed space missions set course for the Moon and beyond, astronauts will experience prolonged exposure to Galactic Cosmic Rays (GCR) and potentially intense Solar Proton Events (SPEs), both of which pose significant short‐ and long‐term health risks.

A Near‐Real‐Time Deep‐Learning Solar Flare Forecasting System Supported by SDO/HMI and ASO‐S/FMG Magnetograms

Space Weather, Volume 24, Issue 10, October 2026.
Abstract This study develops and evaluates five deep learning models, including image‐based (CNN, SwinT) and video‐based (CNN‐LSTM, SwinT‐LSTM, Video SwinT), to forecast ≥ ${\ge} $M‐class flares within the next 24 hr using cross‐validation (CV) data sets.
