G3 – Strong geomagnetic storm following CME impact produced by X9.0 solar flare
The coronal mass ejection (CME) produced by the X9.0 solar flare on October 3, 2024, impacted Earth around 07:30 UTC on October 6, elevating solar wind parameters.
Models show multiple incoming CMEs, G3 – Strong or higher geomagnetic storm forecast
At least three coronal mass ejections (CMEs) are expected to strike Earth from October 5 to 7, prompting a G3 – Strong Geomagnetic Storm Watch, with the possibility of G4 – Severe geomagnetic storm conditions.
CME impacts Earth, sparking G3 – Strong geomagnetic storm and widespread red aurora
Coronal mass ejection (CME) produced by a filament eruption early Sunday, September 8, 2024, hit Earth at around 03:50 UTC on September 12. The impact sparked G3 – Strong geomagnetic storming and widespread red aurora.
Filament eruption produces Earth-directed CME; S1 – Minor solar radiation storm in progres
Early on Sunday, September 8, 2024 (UTC), a magnetic filament erupted from the Sun’s northwest quadrant (N16W22), releasing an Earth-directed coronal mass ejection (CME). The CME is expected to impact Earth on September 10, potentially triggering a G2 – Moderate geomagnetic storm. Concurrently, heightened activity near the Sun’s west limb has caused a sharp increase in proton levels, resulting in an S1 – Minor solar radiation storm at 08:50 UTC today.
Study reveals major impacts of G5 – Extreme geomagnetic storm on satellite operations in May 2024
Researchers from the Massachusetts Institute of Technology (MIT) investigated the significant impacts and scientific insights from the May 2024 G5 – Extreme geomagnetic storm and how it impacted satellite operations and atmospheric activities.
G5 – Extreme geomagnetic storm following strong CME impact
The first of several incoming coronal mass ejections (CMEs) impacted Earth at around 16:56 UTC on May 10, 2024, rapidly increasing geomagnetic field levels from unsettled to G4 – Severe by 17:44 and to G5 – Extreme by 23:34 UTC — something we haven’t seen since 2003.
Two stealth CMEs impact Earth, producing G3 – Strong geomagnetic storm
Two stealth coronal mass ejections (CMEs) impacted Earth over the past 24 hours, sparking G1 – Minor to G3 – Strong geomagnetic storming. A G3 – Strong (or greater) Geomagnetic Storm Warning remains in effect through 21:00 UTC on May 2, 2024.
CME impact sparks unexpected G3 – Strong geomagnetic storm, red aurora in Missouri, U.S.
Solar wind conditions became enhanced beginning at 04:13 UTC on April 19, 2024, due to coronal mass ejection (CME) impact, resulting in unexpected G3 – Strong geomagnetic storming just before 20:00 UTC.
CME impact sparks G2 – Moderate geomagnetic storm
A coronal mass ejection (CME) produced by C5.1 solar flare on February 28, 2024, impacted Earth at approximately 08:45 UTC on March 3, producing G2 – Moderate geomagnetic storming.
Three CMEs heading toward Earth, impact expected on February 13
At least three coronal mass ejections (CMEs) are heading toward Earth. The impact is expected early on February 13 (UTC), producing G2 – Moderate or stronger geomagnetic storming.
