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.
