Humongous solar flare erupts from sun

A spectacular solar flare erupted on the sun Monday, kicking up a massive amount of plasma. 

The sun erupted in an amazing solar flare Monday, unleashing an intense eruption of super-heated plasma that arced high above the star's surface before blasting out into space.

The powerful solar flare occurred at 1:45 p.m. EDT (1745 GMT) and registered as a moderate M1.7-class on the scale of sun storms, placing it firmly in the middle of the scale used by scientists to measure flare strength. The storm is not the strongest this year from the sun, but photos and video of the solar flare captured by NASA spacecraft revealed it to be an eye-popping display of magnetic plasma.

"Great eruption happening on the sun now," scientists with NASA's Solar Dynamics Observatory (SDO) wrote in a Twitter post.

The solar flare erupted along the sun's eastern limb (its left side) from an active region that may also be responsible for solar storm activity observed on Sunday, SDO mission officials said. The flare kicked up a massive amount of solar plasma in an explosion known as a coronal mass ejection, or CME.

"Such eruptions are often associated with solar flares, and in this case an M1 class (medium-sized) flare did occur at the same time, though it was not aimed toward Earth," officials with NASA's Goddard Space Flight Center in Greenbelt, Md., explained in an image description. The Goddard center oversees the sun-monitoring SDO mission.

When aimed at Earth, strong solar flares and CMEs can supercharge the planet's auroras, also known as the northern and southern lights. Extremely powerful CMEs can pose a danger to astronauts and satellites in space, as well as power grids, navigation and communications systems on Earth.

Astronomers measure solar flares on a letter scale, with the strongest events falling into three categories: C, M and X. C-class solar flares are the weakest events, with the X-class sun storms marking the most powerful events on the sun.

The sun is currently in an active phase of its 11-year solar weather cycle and is expected to reach its peak activity in 2013. The current solar weather cycle is known as Solar Cycle 24.

Dear Reader,

About a year ago, I happened upon this statement about the Monitor in the Harvard Business Review – under the charming heading of “do things that don’t interest you”:

“Many things that end up” being meaningful, writes social scientist Joseph Grenny, “have come from conference workshops, articles, or online videos that began as a chore and ended with an insight. My work in Kenya, for example, was heavily influenced by a Christian Science Monitor article I had forced myself to read 10 years earlier. Sometimes, we call things ‘boring’ simply because they lie outside the box we are currently in.”

If you were to come up with a punchline to a joke about the Monitor, that would probably be it. We’re seen as being global, fair, insightful, and perhaps a bit too earnest. We’re the bran muffin of journalism.

But you know what? We change lives. And I’m going to argue that we change lives precisely because we force open that too-small box that most human beings think they live in.

The Monitor is a peculiar little publication that’s hard for the world to figure out. We’re run by a church, but we’re not only for church members and we’re not about converting people. We’re known as being fair even as the world becomes as polarized as at any time since the newspaper’s founding in 1908.

We have a mission beyond circulation, we want to bridge divides. We’re about kicking down the door of thought everywhere and saying, “You are bigger and more capable than you realize. And we can prove it.”

If you’re looking for bran muffin journalism, you can subscribe to the Monitor for $15. You’ll get the Monitor Weekly magazine, the Monitor Daily email, and unlimited access to CSMonitor.com.
