Mysterious Solar Phenomenon We May Have To Worry About

September 23, 2012 1 comment

MessageToEagle.com – Coronal cavities are voids in coronal emission often observed above high latitude filament channels.

Sometimes, these cavities have areas of bright X-ray emission in their centers.

Now, NASA scientists focus on this mysterious phenomenon because it seems to be strongly related to dangerous coronal mass ejections (CMEs).
And CMEs, scientists have to worry about.

Sun Delivered Curveball Of Powerful Radiation At Earth Say UNH Scientists

A potent follow-up solar flare, which occurred Friday (Jan. 17, 2012), just days after the Sun launched the biggest coronal mass ejection (CME) seen in nearly a decade, delivered a powerful radiation punch to Earth’s magnetic field despite the fact that it was aimed away from our planet.According to University of New Hampshire scientists currently studying and modeling various aspects of solar radiation, this was due to both the existing population of energetic particles launched by the first CME and a powerful magnetic connection that reeled particles in towards Earth from the Sun’s blast region, which had spun to an oblique angle.”Energetic particles can sneak around the ‘corner,’ as was the case in Friday’s event when it was launched at the Sun’s limb, or edge,” says astrophysicist Harlan Spence, director of the UNH Institute for the Study of Earth, Oceans, and Space (EOS) and principal investigator for the Cosmic Ray Telescope for the Effects of Radiation (CRaTER) instrument onboard NASA’s Lunar Reconnaissance Orbiter (LRO) mission. CRaTER is designed to measure and characterize aspects of the deep space radiation environment.

NASA will host a media teleconference at 1 p.m. EDT on Wednesday, Sept. 7, to discuss new observations about solar flares that can impact communication and navigation systems.

NASA’s Solar Dynamics Observatory, or SDO, is providing new data and images for scientists to better understand the sun’s dynamic processes, which can affect Earth. The spacecraft launched in February 2010.NASA recently made a breakthrough in sunspot and solar storm predictions.Based on data from the Solar Dynamics Observatory (SDO), this movie shows a sunspot emerging from depth in February 2011.

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…
