Big Sunspots Facing Earth

Source - Space Weather News for Sept. 3, 2017:

SUNSPOT GENESIS: Two big sunspot groups are now facing Earth. Behemoth AR2674 has been growing for days, while newcomer AR2673 has suddenly quadrupled in size, with multiple dark cores breaching the surface of the sun in just the past 24 hours. The rapid development of these regions could herald Earth-directed flares in the days ahead.
