- AR 1476 is big enough for amateur astronomers with decent equipment to spot from their backyards, weather permitting.
- Monday evening's eruption generated an Earth-directed CME, which should hit Earth sometime Wednesday morning (May 9).
- Sunspots are temporary dark patches on the surface of the sun that are caused by intense magnetic activity.
An enormous sunspot group has taken shape on the surface of the sun, hinting that our star may soon start spouting off some powerful storms.
The huge sunspot complex, known as AR 1476, rotated into Earth's view over the weekend. It measures more than 60,000 miles (100,000 kilometers) across, researchers said. Scientists with NASA's Solar Dynamics Observatory mission, a space-based telescope watching the sun, dubbed the solar structure a "monster sunspot" in a Twitter announcement.
