Last night's burst ranked among the strongest of solar cycle 25, at times flirting with G5
0:39
A quick note on the scale. NOAA rates geomagnetic storms G1 through G5
0:45
G4 is severe. Auroras can dip far south, then you may see GPS or radio hiccups
0:51
G5 is extreme. That's when we worry about wider grid stress and satellite drag
0:57
Where to look tonight? NOAA puts the best odds from northern New England through the Great Lakes and upper Midwest to the Pacific Northwest
1:04
That's if the new CME hits as projected. Clouds may spoil views in the northwest, New England, and upstate New York
1:12
The clearer bets? The Dakotas, northern and central Minnesota, Wisconsin, and Michigan
1:18
How rare was it? the storm reached G4 and pushed vivid reds, greens, and purples unusually deep into the U.S.
