Was October 23, 2026 a coronal mass ejection?
NO
No — Earth's magnetic field is quiet (Kp 2.3), with no CME arrival; the next possible glancing blow is this weekend.
Why
- Kp index 2.3 at 09:00 UTC, geomagnetic storm level none
- Past 24 hours peaked at Kp 4, below G1 storm threshold
- A small prominence eruption may reach Earth Oct 24-25
