Solar filament eruption produces Earth-directed CME
An approximately 25 degrees in length filament eruption centered near S35W09, began erupting after 09:00 UTC on January 22, 2024, producing an Earth-directed CME. The estimated time of arrival is January 25.
Complex filament eruption produced Earth-directed CME, impact expected late January 22
A coronal mass ejection produced by a filament eruption on January 20, 2024, is expected to reach Earth late January 22, producing G2 – Moderate geomagnetic storming.
Major X5.0 solar flare erupts from Region 3536 — the strongest flare of Solar Cycle 25
