Solar Flare Disrupts Radio Waves On Earth

February 5, 2013 Comments off
coronal mass ejection

A solar flare drowned out radio communications on Earth on February 2. The relatively “tiny” sun spot erupted into a moderately sized Class-C coronal mass ejection. The sound of the waves created by the solar flare cloaked radio waves between 28MHz and 21.1 MHz.

The voices going across the impacted radio signals appeared to be “swallowed” by the solar flare, Wired notes. NASA JOVE project radio astronomer Thomas Ashcraft noted how interesting the sound was as the wave from the coronal mass ejection (CME) rolled through.

As previously reported by The Inquisitr, the sun is entering the Read more…

SOLAR WATCH: Monster Sunspot 1654 Aims Our Way – Earthquake Window Opening As Coronal Mass Ejections To Hit Earth On Thursday!

January 15, 2013 – THE SUN – Simulations of a coronal mass ejection (CME) show the impact arrival of such on January 17th. This coincides with Senior Meteorologist Kevin Martin’s window for an earthquake in North America. The Sun is acting up again, with large sunspots moving across the solar disk. The sunspots are powerful enough for x-class solar flares, the most powerful of them all.

While a 10% chance is now given for such a flare, one is already on the way. This should impact on January 17th and Read more…

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.

Scientists Expect A Massive Solar Event To Hit By Next Year

It was in January 1994 that two Canadian telecommunications satellites blanked out during a major sunburst while in geosynchronous orbit and communications were disrupted nationwide.

While recovery occurred after only a few hours on the first satellite, it took some six months and more than $70 million to recover the second satellite.

Then in January 2005, some 26 United Airlines flights had to be diverted during a space weather storm to non-polar routes – to avoid the prospect of high frequency radio blackouts.

Added were landings and takeoffs, flight time and other factors that elevated fuel consumption and costs. Each route change ended up costing more than $100,000.

Then in February 2011, there was a sun eruption experts described as the largest solar flare in four years. It caused interference in radio communications and global positioning system signals for aircraft traveling long-distances.

While it was a modest outburst, experts say it signaled the beginning of an upcoming Read more…

Giant Cube Recorded By NASA, Bigger Than Earth, Near Sun On Dec 21st & 23rd. NASA Source, Alien Cube First Seen In 2011

Very interesting as I am extremely curious as what this could be…

Posted by Scott C. Waring, Author UFO Sightings Daily

Date of sighting: December 21, 2012
Location of sighting: Earths Sun
I was looking at the NASA/SOHO images and noticed that the black cube is back. This is on the NASA site right now so if you want to check for yourself please click the link below. This cube has been seen near the sun several times a month. Odd that it chose Dec 21, 2012. Sometimes this cube even is three dimensional so you can see it is really a cube. It is black because it is not hot like Read more…

Mysterious Solar Phenomenon We May Have To Worry About

September 23, 2012 1 comment

messagetoeagle

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.

Sunspots Can Trigger Frigid Winters in Europe

August 31, 2012 Comments off

climatecentral.org

A major part of the climate change that scientists have documented over the past few decades comes from human emissions of heat-trapping greenhouse gases. Not all of it, however. Natural climate cycles haven’t magically disappeared — the El Niño/Southern Oscillation, or ENSO, for example, is entering a phase that will likely boost global temperatures temporarily — and scientists are still discovering new ones.

The latest comes in a new report published in Geophysical Research Letters. It’s well known that the Sun varies slightly in brightness every 11 years, and while those changes pale beside the effect of human-generated greenhouse gases, according to the report, they’re enough to trigger unusually cold winters in Central Europe.

 

The smoking gun is the freezing of the Rhine river, something that doesn’t happen often because it’s difficult to freeze such a large, free-flowing volume of water. Those unusually cold winters might come along at random, but by looking back at records dating to all the way back to 1780, a Read more…

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…

Scientists Stumped By Sun’s Asymmetrically Reversing Magnetic Field

April 27, 2012 2 comments

The Sun’s magnetic field is reversing, South becoming North, as it does approximately every 11 years on a cycle, but this time, something even stranger is going on: The North is moving much faster than the South, and space scientists aren’t sure why.

“Right now, there’s an imbalance between the north and the south poles,” Jonathan Cirtain, NASA’s project scientist for a Japanese solar mission called Hinode, in a recent article on NASA’s website. “The north is already in transition, well ahead of the south pole, and we don’t understand why.”

Further, the asymmetrically reversing solar magnetic field could have an effect on Earth, resulting in increased solar flares and the accompanying bursts of radioactive particles called “coronal mass ejections,” or CMEs, that can hit Earth and cause brilliant Northern Lights displays and problematic geomagnetic solar storms, according to NASA scientists.

“This usually leads to a double peak in the sunspot number and CME rate as a function of time,” Nat Gopalswamy, a solar scientist NASA’s Goddard Space Flight Center in Greenbelt, Md., in an email to TPM.

Gopalswamy and his team studied the Sun’s shifting magnetic field from Read more…

INDIALANTIC — Atomic particles explode off the sun’s surface, with the force of millions of hydrogen bombs, clobber Earth’s magnetic field in less than a day and black out the electric grid for days or longer.

Such a solar “super storm” happened in 1859. Called the Carrington Event, solar wind smacked the Earth within 18 hours, though the trip usually takes four days. Auroras lit the night sky as far south as Cuba, and in Boston and London, people read the newspaper under the nighttime glow.

A similar event now could cause $2 trillion in damage to Read more…
