Note: Likely outflow associated with CME: 2025-02-23T02:36Z, an eruption associated with an M4.9-class flare from AR 14001 which peaked at 2025-02-23T02:13Z at N25W82. Beginning around 2025-02-23T02:09Z, wide opening field lines and small post-eruptive arcade are observed in SDO AIA 171/193. Triangulation with STEREO Ahead suggests the eruption is sourced around W55 but this is not supported by EUV imagery.
