Sunspot AR1654 Getting Bigger, Unleashes Solar Flare In M1-Class Blast, NASA Officials Say

Solar Flare

This view of the flare on Jan. 11, 2013, was recorded by NASA’s Solar Dynamics Observatory.

The surface of the sun erupted in a solar flare early today (Jan. 11), unleashing a blast of super-heated plasma into space.

A huge sunspot known as AR1654 produced the M1-class flare at 4:11 a.m. EST (0911 GMT), officials with NASA’s Solar Dynamics Observatory said in a description of the event. The SDO spacecraft is one of several sun-watching space telescopes keeping tabs on solar flares and other sun weather events.

According to Spaceweather.com, sunspot AR1654 is growing more active and is now “crackling with M-class solar flares” like the one that erupted today.

Huge SUNSPOT 1476 poses a threat(Video)

May 8, 2012 Comments off

spaceweather.com

BIG SUNSPOT: One of the largest sunspot groups in years rotated over the sun’s northeastern limb this weekend. With a least four dark cores larger than Earth, AR1476 sprawls more than 100,000 km from end to end, and makes an easy target for backyard solar telescopes. Amateur astronomer Alan Friedman sends this picture of the behemoth from his backyard in Buffalo, NY: “AR1476 is firecrackler,” says Friedman. Indeed, the active region is crackling with impulsive M-class solar flares. Based on the sunspot’s complex ‘beta-gamma’ magnetic field, NOAA forecasters estimate a 75% chance of Read more…

Nasa’s Solar Dynamics Observatory (SDO) has captured the stunning images of solar flares from the Sun on 16 April.

The flares kicked up a massive amount of intense super-heated solar plasma in an explosion known as coronal mass ejection, or CME. The eruptions blasted off the east limb (left side) of the Sun.

The powerful solar flare occurred at 1:45 p.m. EDT (17:45 GMT) and registered a M1.7 class (medium-sized) on the scale scientists used to measure flare strength, said Nasa.

“A large coronal mass ejection blasts off over the eastern limb of the Sun. Great eruption happening on the Sun now,” Nasa scientists posted a message on twitter.

Coronal mass ejections are associated with solar flares and can also occur independently. Both the solar flares and coronal mass ejections occur as a result of Read more…

Could The Sun Set Off The Next Big Natural Disaster?

It can take a long time to clean up from natural disasters. New Orleans still had remnants of Katrina damage years after the storm barreled through. Hundreds of thousands of people are still homeless in Haiti, more than a year and a half after its earthquake. Areas of Japan may be off limits for years due to the earthquake/tsunami/nuclear disaster at Fukushima.

But as bad as these events might be, they are at least limited geographically. But that probably won’t be true when it comes to a severe solar storm, say scientists in a new study in Space Weather. Before I go into that, though, let’s first review what I mean by Read more…

Shape-shifting sunspot 1271 harbors energy for M-class solar flares

August 24, 2011 Comments off

Every time you look, sunspot 1271 has a new outline. For the past two days the active region has been in a constant state of change, altering its shape on an hourly basis. Click on the image for 48 hours of shape-shifting:

These rapid changes have caused the sunspot’s magnetic field to criss-cross and tangle. The magnetic field now has a “beta-gamma” configuration that harbors energy for M-class solar flares. Any such flares today would be approximately Read more…

New method detects emerging sunspots deep inside the sun, provides warning of dangerous solar flares news

August 20, 2011 Comments off

Sunspots spawn solar flares that can cause billions of dollars in damage to satellites, communications networks and power grids.

But Stanford researchers have developed a way to detect incipient sunspots as deep as 65,000 kilometers inside the sun, providing up to two days’ advance warning of a damaging solar flare.

Viewed from the technological perspective of modern humans, the sun is a seething Read more…
