BREAKING: Earth just got slapped by a G4 #geomagnetic storm.
A massive solar eruption (CME, 1938 km/s) hit Earth’s #magnetosphere on June 1, triggering a Severe G4-class storm, confirmed by NOAA and others.
What it means:
- Power grid instability above 45° latitude
- #Satellite disruptions and GPS drift
- #Radio blackouts
- Auroras as far south as California and Alabama
Kp index hit 8+, flirting with 9. G4 alerts remain active through June 2. Expect fallout, then gradual easing to G1-G2 by June 3.
Space weather isn’t just pretty lights. It’s infrastructure roulette #nostr.
