The largest sunspot to appear on Earth's nearest star in more than two decades is once again pointed at the planet, and it will likely kick-start solar storms, NASA scientists say.
The massive sunspot, previously known as Active Region 12192, was turned toward Earth in October and early November, but rotated out of view. While it was on the Earth-facing side of the sun, the sunspot did not produce any coronal mass ejections — hot bursts of material ejected into space at 4 million mph (6.4 million kilometers/hour) — which have the potential to damage satellites and power grids. Now the active region has rotated back around to face Earth again, and although the sunspot has shrunk in size, it will likely be disruptive, NASA scientist Holly Gilbert told Space.com during a video interview about the massive sunspot Read more...
