Multiple coronal mass ejections (CMEs) — of which at least 4 halo CMEs produced by Active Region 3664 over the past few days — will hit Earth, starting late May 10 into May 11, 2024.
At least five coronal mass ejections (CMEs) produced over the past 3 days are heading toward Earth. The first impact is expected on May 9 and the following over the next 3 – 4 days.
A major solar flare measuring X1.0 erupted from Active Region 3664 at 05:09 UTC on May 8, 2024. The event started at 04:37 and ended at 05:32 UTC. Preliminary modeling efforts showed CME arrival time early on May 11. This is the second X-class solar flare of the day, following another X1.0 at 01:41 UTC.
A powerful, long-duration solar flare measuring X4.5 erupted from Active Region 3663 at 06:35 UTC on May 6, 2024. The event started at 05:38 and ended at 06:47 UTC.
A major solar flare measuring X1.2 erupted from Active Region 3663 (beta-gamma-delta) at 11:54 UTC on May 5, 2024. The event started at 11:41 and ended at 12:16 UTC. This is the second X-class solar flare of the day and the third from Region 3663 since X1.6 on May 3.
A major solar flare measuring X1.3 erupted from Active Region 3663 at 06:01 UTC on May 5, 2024. The event started at 05:47 and ended at 06:09 UTC. This is the second X-class solar flare from this region since X1.6 at 02:22 UTC on May 3.
A major solar flare measuring X1.6 erupted from Active Region 3663 (beta-delta) at 02:22 UTC on May 3, 2024. The event started at 02:11 and ended at 02:27 UTC. A G1 – Minor geomagnetic storm is in effect for May 5 and a G2 – Moderate for May 6 (UTC day) due to the potential arrival of a CME produced by this flare.
A strong X1.1 solar flare erupted from Active Region 3615 at 20:56 UTC on March 28, 2024. The event started at 20:50 and ended at 21:01 UTC.
Coronal mass ejection (CME) produced by the X1.1 solar flare at 01:33 UTC on March 23, 2024, is expected to impact Earth late March 24 or early March 25, producing G2 – Moderate to G3 – Strong geomagnetic storming.
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.
