Multi‐Source Forecast of Solar Cycle Flare Activity Using the Novel Informer‐Based Models

Space Weather, Volume 23, Issue 4, April 2025.
Abstract Solar flares, the significant indicators of solar activity, have an impact on Earth's satellites and communication systems. Accurate prediction of solar flare events is crucial for mitigating these effects. In this work, we use multiple data sources, including Geostationary Operational Environmental Satellites soft X‐ray flare flux and the ...

Risk Assessment of the Ground Magnetic Response to the March and April 2023 Geomagnetic Storms Using Geomagnetically Induced Currents Indices

Space Weather, Volume 23, Issue 4, April 2025.
Abstract We analyzed the solar origin and ground response during the severe geomagnetic storms (GSs) of 23–24 March (GS1) and 23–24 April 2023 (GS2) using Geomagnetically Induced Currents Indices (GIC indices) computed from geomagnetic field data. The GSs were initiated by erupting filaments and associated slow (fast) halo coronal mass ejections on 20 ...

Comparative Analysis of Type III Radio Bursts and Solar Flares: Spatial Localization and Correlation with Solar Flare Intensity

The Astrophysical Journal
We present a comprehensive study of type III radio bursts and their association with solar flares of magnitude M1.0 and larger, as observed by four widely separated spacecraft (Parker Solar Probe, Solar Orbiter, STEREO-A, and Wind). Our main focus is the

Two Types of Solar Confined Flares [PDF]

arXiv, 2019
With the aim of understanding the physical mechanisms of confined flares, we selected 18 confined flares during 2011-2017, and classified the confined flares into two types based on their different dynamic properties and magnetic configurations. "Type I" of confined flares are characterized by slipping reconnection, strong shear, and stable filament ...

Should We Monitor Space Weather Effects on Surveillance Technologies Used in Air Traffic Management?—First Results

Space Weather, Volume 23, Issue 4, April 2025.
Abstract Space weather events can disrupt satellite navigation, potentially compromising also the accuracy of real‐time flight tracking via Automatic Dependent Surveillance‐Broadcast (ADS‐B). This in turn could limit the situational awareness of pilots and reduce the efficiency of the air traffic management.

Detecting the Sun’s active region using image processing techniques

Physical Sciences and Technology, 2021
The term ‘space weather’ refers to adverse conditions on the Sun that could affect the structures of space or terrestrial technology and risk human health or life. Flares produce effects that span the electromagnetic spectrum.

Comparison of Solar Energetic Particle Flux Measurements by CRaTER and GOES

Space Weather, Volume 23, Issue 4, April 2025.
Abstract The Cosmic Ray Telescope for the Effects of Radiation (CRaTER) aboard the Lunar Reconnaissance Orbiter spacecraft has been operating in lunar orbit since 2009. CRaTER data provide a long‐term record of the near‐Moon radiation environment that is relevant to human exploration.
