Monster Sunspot Threatens to Unleash Powerful Solar Flares

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.
AR 1476 is big enough for amateur astronomers with decent equipment to spot from their backyards, weather permitting. (Warning: Never look at the sun directly with telescopes or the unaided eye. Special filters are required for safe solar viewing to avoid serious eye damage.)
"With at least four dark cores larger than Earth, AR 1476 sprawls more than 100,000 km from end to end, and makes an easy target for backyard solar telescopes," the website Spaceweather.com [ http://spaceweather.com/ ] reported Monday (May 7).
