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

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…

Powerful Solar Flare Could Have Caused Serious Damage: Earth ‘Lucked Out’

August 10, 2011 Comments off

The sun unleashed its most powerful solar flare in four years Tuesday — an eruption that could have had serious consequences on Earth if it had taken place on the side of the sun facing the planet.

“We lucked out because the site of the eruption at the sun was not facing the Earth, so we will probably feel no ill effects,” Joe Kunches, a space scientist with the National Oceanic and Atmospheric Administration’s Space Weather Prediction Center, told MSNBC.

So far, it appears that any consequence felt on the Earth will not cause human injury. A minor proton storm currently on the Earth’s surface could affect satellites in high-altitude orbits, and radiation briefly disrupted Read more…

MAJOR SOLAR FLARE: August 9th, 2011.

This morning at 0805 UT, sunspot 1263 produced a powerful X7-class solar flare. NASA’s Solar Dynamics Observatory captured the explosion’s extreme ultraviolet flash.

The solar flare was not Earth directed but a minor proton storm is in progress around our planet, which could affect satellites.

Radiation from the flare also briefly disrupted communications on some VLF and HF radio frequencies.

We may get a glancing blow from the flare. Read more…

A Strong M-class solar flare headed for Earth

STRONG SOLAR ACTIVITY: For the third day in a row, active sunspot 1261 has unleashed a strong M-class solar flare. The latest blast at 0357 UT on August 4th registered M9.3 on the Richter Scale of Flares, almost crossing the threshold into X-territory (X-flares are the most powerful kind). The number of energetic protons around Earth has jumped nearly 100-fold as a result of this event. Stay tuned for updates.

INCOMING CLOUDS: At least two coronal mass ejections (CMEs) are now en route to Earth, propelled toward us by eruptions in the magnetic canopy of sunspot 1261 on August 2nd and 3rd. Analysts at the GSFC Space Weather Lab have just produced a new 3-D model of the advancing CMEs. Click on the image to set the clouds in motion below:

Solar Threat: We’ll Have Minutes to Respond; Government Plans Controlled Blackouts; Elite Contingency Plans

While many will claim that solar storms are an unrealistic threat to our world, the governments of the United States and the United Kingdom aren’t taking any chances.

According to a report put together by Alex Thomas of The Intel Hub, the threat is not only real, but very likely, and could change the world as we know it from one day to the next:

In a stunning announcement, The United States and United Kingdom are likely set to began “controlled” power cuts in preparation of a giant solar storm.

The announcement by Thomas Bogdan, the director of the US Space Weather Prediction Centre, comes a week after a large scale solar flare released a massive amount of radiation and threatened to cause moderate disruption.

The solar flare on June 7th, 2011 was luckily pointed away from Earth but caused Read more…

‘Dramatic’ solar flare could disrupt Earth communications

Handout photo released by NASA Earth Observatory on June 7, 2011 and taken from NASA's Solar Dynamics Observatory (SDO), sunspot complex 1226-1227, shows the Sun unleashing an M-2 (medium-sized) solar flare.

WASHINGTON – An unusual solar flare observed by a NASA space observatory on Tuesday could cause some disruptions to satellite communications and power on Earth over the next day or so, officials said.

The potent blast from the Sun unleashed a firestorm of radiation on a level not witnessed since 2006, and will likely lead to moderate geomagnetic storm activity by Wednesday, according to the National Weather Service.

“This one was rather dramatic,” said Bill Murtagh, program coordinator at the NWS’s Space Weather Prediction Center, describing the M-2 (medium-sized) solar flare that peaked at 1:41 a.m. Eastern time in North America, or 0541 GMT.

“We saw the initial flare occurring and Read more…

Solar storms may wreak havoc on Earth in 2013: Scientists

May 20, 2011 Comments off

The intensity of solar storms is expected to peak in 2013 and may devastate critical infrastructure like satellite communications, navigation systems and electrical transmission equipment, a top scientist has warned. Kathryn Sullivan, assistant secretary of the US National Oceanic and Atmospheric Administration, said countries should prepare for “potentially devastating effects” from solar storms which are caused by massive explosions on the sun.

Solar storms, according to scientists, release particles that can temporarily disable or permanently destroy fragile computer circuits, the Daily Mail reported.

Dr Sullivan, a former NASA astronaut who in 1984 became the first woman to walk in space, told a UN weather conference in Geneva that “it is not a question of if, but really a matter of when a major solar event could hit our planet”. She is not the only expert to issue a warning about the threat posed by solar storms. In February, astronomers warned that mankind is now more vulnerable to such an event than at any time in history — and that the planet should prepare for a global Hurricane Katrina-style disaster.

A massive solar eruption, they said, would send waves of radiation and charged particles to Earth, damaging satellite systems used for synchronising computers, airline  navigation and phone networks. If the storm is powerful enough it could even crash stock markets and cause power cuts that last weeks or months, experts told the American Association for the Advancement of Science.

The chances of a disruption from space are getting stronger because the sun is entering the most active period of its 11 to 12-year natural cycle. The world got a taster of the sun’s explosive power in February when the strongest solar eruption in five years sent a torrent of charged plasma hurtling towards the world at 580 miles per second. The storm created spectacular aurorae and disrupted radio communications.

Space storms are not new. The first major solar flare was recorded by British astronomer Richard Carrington in 1859. Other solar geomagnetic storms have been observed in recent decades. According to NASA, one huge solar flare in 1972 cut off long-distance telephone communication in the mid-western state of Illinois. Another similar flare in 1989 ‘provoked geomagnetic storms that disrupted electric power transmission’ and caused blackouts across the Canadian province of Quebec, the US space agency said.
