Was today the aurora visible tonight?
Checking
NO
No — the Kp index peaked at just 4.3 overnight, well below the Kp 7 needed at Columbus latitudes.
Why
- Current planetary K-index: 1.33, no geomagnetic storm
- Past-24h peak Kp 4.33 — aurora stays near the Arctic
- Moon 98% illuminated, bright enough to swamp faint aurora
