G4 – Severe geomagnetic storm in progress
A coronal mass ejection (CME) produced on June 25, 2024, impacted Earth shortly after 09:30 UTC on June 28, producing G4 – Severe geomagnetic storm.
X1.7 and long duration M6.6 solar flares erupt from Region 3664, solar radiation storm in progress
Active Region 3664 — the source of numerous Earth-directed coronal mass ejections (CMEs) over the past 7 days — began its transit of the western limb on May 13, 2024. The region remains very active, producing a long-duration M6.6 flare on May 13, associated with a likely Earth-directed CME, and an X1.7 at 02:09 UTC on May 14. Meanwhile, a solar radiation storm is in progress due to activity associated with the same region.
From dusk till dawn with all-sky camera in Italy observing exceptional auroral activity in 4K
Thanks to Gianluca Masi of the Virtual Telescope Project, we have an exceptional video showcasing auroral activity from May 10 and 11, 2024, during a G5 – Extreme geomagnetic storm.
Powerful X5.8 solar flare erupts from Region 3664 during G5 – Extreme geomagnetic storm
A major solar flare measuring X5.8 erupted from Active Region 3664 at 01:23 UTC on May 11, 2024. The event started at 01:10 and ended at 01:39 UTC. It took place during G5 – Extreme geomagnetic storm, producing another CME — most likely Earth-directed.
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.
G2 – Moderate geomagnetic storm levels forecast as two more CMEs approach Earth
Solar wind parameters in 24 hours to 00:30 UTC on April 17, 2024, continued to be enhanced by a passing coronal mass ejection (CME) which impacted Earth around 17:25 UTC on April 15 (launched from the Sun on April 12). Two more CMEs, produced on April 14 and 15, are expected to make a combined impact at around 00:00 UTC on April 18.
ESA’s SMOS and Swarm observe strongest geomagnetic storm since 2017
The European Space Agency’s SMOS and Swarm satellites have, for the first time, successfully tracked a severe solar storm, following an X1.1 solar flare and a halo coronal mass ejection (CME) on March 23, 2024. The CME impacted Earth on March 24, producing a G4 – Severe geomagnetic storm — the strongest geomagnetic storm since September 2017.
Major, long-duration X1.1 solar flare produces Earth-directed CME
A major, long-duration solar flare measuring X1.1 erupted from Active Region 3614 at 01:33 UTC on March 23, 2024. The event started at 00:58 and ended at 02:21 UTC. A halo CME was produced, with impacts to Earth likely late March 25 or early March 26.
