Ionospheric Response to the 8 April 2024 Total Solar Eclipse: Plasma Depletion and Eclipse‐Driven MsTIDs

Space Weather, Volume 24, Issue 4, April 2026.
Abstract The total solar eclipse on 8 April 2024 provided a unique opportunity to investigate the three‐dimensional (3‐D) ionospheric response under enhanced solar activity over North America. In this study, we processed high‐density GNSS observations from ∼1,700 stations to derive vertical total electron content and applied a multi‐term sinusoidal ...

Automatic Identification of Interplanetary Shocks Based on Machine Learning

Space Weather, Volume 24, Issue 4, April 2026.
Abstract Fast forward interplanetary shocks (FFs) are one of the primary drivers of space weather events. This study presents an automated detection algorithm for FFs based on a multilayer perceptron model, utilizing in situ measurements of interplanetary magnetic fields and solar wind plasma from the Wind spacecraft at 1 AU.

Climatology of Plasma Irregularities Using ROTI Index From 2008 to 2023 in East West Asia

Space Weather, Volume 24, Issue 4, April 2026.
Abstract This study investigates characteristics of ionospheric irregularities over the East–West Asian equatorial region using the Rate of TEC Index (ROTI) derived from Global Navigation Satellite System (GNSS) measurements. Data from four stations (GUAM, PIMO, CUSV, and IISC) were analyzed for 2008–2023, covering solar cycle (SC) 24 and the ascending

Unraveling Super Equatorial Plasma Bubbles (EPBs) Evolution During the 23 April 2023 Storm: Multi‐Instrument Observations and GITM‐SAMI3 Simulation

Space Weather, Volume 24, Issue 4, April 2026.
Abstract Storm‐time equatorial plasma bubble (EPB) dynamics play a critical role in space weather impacts on communication and navigation systems, yet the mechanisms governing their formation and evolution under storm conditions remain poorly understood.
