"Sunspot AR4366 Final Strike!
February 8 Aurora - Northern Lights Reach Seattle, Toronto, Boston"
"After two weeks of relentless bombardment, sunspot region AR4366 has delivered its spectacular farewell performance. This video covers the complete story of the most active sunspot of Solar Cycle 25, which just produced ten X-class flares in nine days before rotating out of Earth-facing position.
The final CME impact arrived exactly on schedule, triggering stunning auroral displays across Seattle, Toronto, Boston, Chicago, and cities that rarely see northern lights. Green curtains danced overhead from the northern tier to unexpected southern latitudes as AR4366’s last Earth-directed plasma wall slammed into our magnetosphere.
We break down the incredible statistics: fifteen Earth diameters wide at peak, beta-gamma-delta magnetic complexity, over sixty significant eruptions including an X8.1 flare ranking as the third-largest of this solar cycle, and continuous radio blackouts affecting communications worldwide for two straight weeks.
Now solar rotation is carrying this beast away from Earth. The explosive growth has stopped. The region is shrinking. And any future flares will send CMEs harmlessly into space. But the story isn’t over - AR4366 could return on the sun’s eastern limb in late February if it survives its far-side transit.
This is space weather history in the making. From emergence to explosive peak to finale, this video documents the complete AR4366 chapter with scientific analysis, forecast verification, and what to expect next as we enter the calm after the storm. Perfect for aurora enthusiasts, space weather followers, and anyone wanting to understand the most intense solar activity period Solar Cycle ."
