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.
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…
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…

The wave of solar storms that has pounded Earth over the past several weeks is only likely to get worse over the next year, according to a NASA scientist.
Sunspot 1429, the active region of the sun responsible for the flares, has been getting larger over the past several weeks, making it less stable and more likely for additional flares to erupt, which can cause damage to GPS satellites and electronic systems on our planet. NASA reported that the sunspot is now more than seven times the width of earth.
“The larger [the active region] is, the more likely it’s going to produce another big flare,” Phillip Chamberlin, deputy project scientist for the Solar Dynamics Observatory says. “It’s growing, and it’s becoming more dynamic, building energy.”
Over the weekend, two large flares erupted from the region. NASA says the wind and energy particles associated with the flare, began to affect Earth Monday. The region is dangerous for Read more…
According to NASA, A solar flare is defined as a “sudden, rapid, and intense variation in brightness”, which occurs when “magnetic energy that has built up in the solar atmosphere is suddenly released.”
For centuries, solar flares have caused various calamities on Earth, such as disrupted communications, blackouts and unusual lights appearing in the sky.
In 1859, the most powerful solar flare in recorded history hit Earth and was observed by the English amateur astronomer Richard Christopher Carrington. It became known as the “Carrington Event”, or as the “Carrington Super Flare”.
The event occurred during solar cycle 10, the tenth solar cycle since 1755.
The powerful solar storm not only created auroras across the world, but also interrupted telegraphs for weeks. That was back in the mid-nineteenth century.
Can you imagine, with the modern reliance on satellites, how devastating such a Read more…
