Sunspot AR2665, which emerged just a few days ago, has mushroomed into a behemoth nearly as wide as the planet Jupiter.
On July 9th the fast-growing sunspot produced an M-class solar flare and a short-lived shortwave radio blackout over east Asia and Australia.
Stronger flares and Earth-directed CMEs may be in the offing as AR2665 turns toward our planet in the days ahead.
