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.
