X1.7 and long duration M6.6 solar flares erupt from Region 3664, solar radiation storm in progress

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.

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.

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.

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.

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.
