Auroras on the Move: Lights Reach Far South Tonight
TL;DR Summary
A powerful X-class solar flare and a fast coronal mass ejection could spark auroral displays much farther south than usual tonight—potentially visible from parts of California, the central Plains, and the Mid-Atlantic, with even deeper-south areas possible. NOAA has issued a rare G4 geomagnetic storm potential, though whether the CME hits Earth head-on remains uncertain. For best viewing, find a dark, clear sky along the northern horizon after sunset.
