WHAT! Sunspot Blasting Out Major Solar Flares Will Face Earth Soon ?

The super-active sunspot responsible for unleashing the three most powerful solar flares of 2013 within a 24-hour stretch this week is slowly rotating toward Earth and will likely be facing our planet by the weekend, experts say.

Active Region 1748, as the sunspot is known, unleashed three monster solar flares between Sunday and Monday (May 12 to 13). Every one of the solar storms registered as an X-class flare — the most powerful type — with each successive event stronger than the last, culminating in an X3.2 megablast Monday night.

These solar explosions did not affect Earth, since AR1748 was not facing our planet at the time. But the sunspot is now circling into view, so future flares and any associated eruptions of super-hot solar plasma — called coronal mass ejections (CMEs) — could potentially target our planet, scientists say.

"In a couple of days, it will be far enough onto the disk that any CMEs that we got would probably have some impact on Earth," solar astrophysicist C. Alex Young, of NASA's Goddard Space Flight Center in Greenbelt, Md., told SPACE.com.

AR1748 should be near the center of the solar disk by around Saturday, Young added.
