    NASA ^ | April 2-3, 2017 | Staff
    The sun emitted a trio of mid-level solar flares on April 2-3, 2017. The first peaked at 4:02 a.m. EDT on April 2, the second peaked at 4:33 p.m. EDT on April 2, and the third peaked at 10:29 a.m. EDT on April 3. NASA’s Solar Dynamics Observatory, which watches the sun constantly, captured images of the three events. Solar flares are powerful bursts of radiation. Harmful radiation from a flare cannot pass through Earth's atmosphere to physically affect humans on the ground, however — when intense enough — they can disturb the atmosphere in the layer where GPS and...

    Surely there is no remedy to this potential danger or the federal government would take necessary precautions to protect us against this threat. After all, isn’t that precisely why government exists in the first place, to keep us safe? The good news is that protective equipment for the civilian grid is available and can be installed in a timely manner. The bad news is that the departments of Homeland Security and Energy have done little so far to protect us against this very real danger.

    Phil PlaitNovember 16, 2015 A new study says that violent space weather that could cost $2 trillion in damage is more common than previously thought In the years 774 and 993, the Earth was attacked from space. Not by aliens, but by a natural event—and it was very, very powerful. Whatever it was, it subtly altered the chemistry of our planet’s atmosphere, creating trace amounts of radioactive elements like chlorine-36, beryllium-10, and carbon-14. And those provide the clue to what the event was: Those isotopes are created when high-energy protons slam into our air. That means the source must have...

    Livescience ^ | Friday, June 29, 2012 | Life's Little Mysteries Staff
    According to an Old English manuscript chronicling the history of the Anglo-Saxons, a mysterious "red crucifix" appeared in the "heavens" over Britain one evening in A.D. 774. Now astronomers say it may have been the supernova explosion that sprinkled unexplained traces of carbon-14 in tree rings that year, halfway around the world in Japan. Jonathon Allen, an undergraduate student at the University of California, Santa Cruz, made the connection this week after listening to a Nature podcast. He heard a team of Japanese scientists discussing new research in which they measured an odd spike in carbon-14 levels in tree rings...

    Nature ^ | Sunday, June 3, 2012 | Richard A. Lovett
    Just over 1,200 years ago, the planet was hit by an extremely intense burst of high-energy radiation of unknown cause, scientists studying tree-ring data have found. The radiation burst, which seems to have hit between AD 774 and AD 775, was detected by looking at the amounts of the radioactive isotope carbon-14 in tree rings that formed during the AD 775 growing season in the Northern Hemisphere. The increase in 14C levels is so clear that the scientists, led by Fusa Miyake, a cosmic-ray physicist from Nagoya University in Japan, conclude that the atmospheric level of 14C must have jumped...

    In the late summer of 1859, an extreme geomagnetic storm bombarded the planet, igniting the ghostly, emerald lights of the aurora across skies as far south as Cuba. These powerful solar eruptions of magnetized plasma hitting the Earth caused telegraph wires to spark, disabled communications and set fire to several telegraph offices, according to NASA In the modern world, the threat of space weather is far greater as storms like the Carrington Event of 1859 pose a risk to interconnected power grids, airline operations, satellites and communications networks across the globe. "The overall goal is to ensure that the nation...

    The sun has had three major solar flares on its surface in the past two days that have affected communications on Earth and could send a shockwave through Earth this Friday, according to the National Oceanic and Atmospheric Administration. The “solar events” caused brief blackouts in high frequency communications when they struck, twice on Tuesday morning and once this morning, all between the hours of 7 a.m. and 9 a.m. EDT.

    One of the STEREO (Solar TErrestrial RElations Observatory) spacecraft stopped phoning home to Earth on Oct. 1 “immediately after a planned reset of the spacecraft”, NASA said in an update last week. .... NASA didn’t say how badly solar weather forecasts are affected, but in other materials they have said both STEREO spacecraft are a crucial part of this work. STEREO’s pair of satellites ... aim to better map Sun eruptions ( “coronal mass ejections”) whose charged particles can disrupt satellite communications during solar storms. The mission has been ongoing since 2006 and they’ve viewed the far side of the...

    The immediate burst of energy from the big flare yesterday had some effect on high frequency radio waves already (check out the first image in the gallery above), according to NOAA’s Space Weather prediction Center, but the hard-to-take CME particles are likely to go just above the Earth, singing us just a bit. The Associated Press reports: New calculations from satellite data show that the worst of the energetic particles streaming from the sun likely will go north or above Earth this time, , said Tom Berger, director of the Space Weather Prediction Center late Wednesday. So while the power...

    The sun unleashed two major solar flares early Tuesday (June 10) in amazing back-to-back storms from our nearest star. The first flare, a powerful X2.2-class solar flare, hit its maximum at about 7:42 a.m. EDT (1142 GMT). The second powerful X1.5-class flare, followed quickly behind, blasting out from the sun at 8:36 a.m. EDT (1236 GMT). Both flares could cause radio communication blackouts on Earth for about an hour, according to an alert from the U.S. Space Weather Prediction Center in Boulder, Colorado. NASA's sun-observing Solar Dynamics Observatory captured a video of the flares from space. "Solar flares are powerful...

    There are various stories about how powerful solar flares were, starting in 2012. Maybe they had an impact on the North Pole or South Pole. Maybe such an effect impacting how cold the winter of 2013/2014 has been. The previous winter -- from December 2012 to March 2013, was initially mild. Then the weather in the Spring was a little bit more chilly. Is it possible that Solar Flares affect the earth's poles. And in affecting the earth's poles, maybe they effect the weather. Anything is possible, and it is up to science to investigate such links. Maybe it would...

    Within a year, nine out of 10 Americans could be dead. And whatever causes the national apocalypse—be it North Korean malice or the whims of the sun—the downfall will ultimately be our own fault. That's the fear of Newt Gingrich and other members of a high-profile coalition who are convinced that our fragile electrical grid could be wiped out at any moment. Their concern? Electromagnetic pulses, the short bursts of energy—caused by anything from a nuclear blast to a solar flare—that can wreak havoc on electrical systems on a massive scale. And the coalition believes it's coming soon.

    The so-called X-class flare erupted a few hours ago (at 7:25 p.m. EST Feb. 24, or 12:25 a.m. UTC Feb. 25) and was captured by several spacecraft. If you have a pictures of the sun yourself to share, feel free to post them in the Universe Today Flickr pool. NASA’s Solar Dynamics Observatory saw the flare growing in at least six different wavelengths of light, which are visible in the image above. This is classified this as an X4.9-class flare, which shows that it is pretty strong. X-flares are the most powerful kind that the sun emits, and each X...

    STORM WARNING: NOAA forecasters estimate a 90% chance of geomagnetic storms on Jan. 9th when a CME is expected to hit Earth's magnetic field. The speed of the solar wind around Earth could spike to 700 km/s (1.6 million mph) shortly after the impact, sharply compressing Earth's magnetosphere. High-latitude sky watchers should be alert for auroras. http://spaceweather.com/ HUGE SUNSPOT, CHANCE OF FLARES: The source of the incoming CME is AR1944, one of the largest sunspots of the current solar cycle. The active region sprawls across more than 200,000 km of solar terrain and contains dozens of dark cores. The largest...

    Over the past several days the Sun has unleashed more than half a dozen major flares including four X-class events. The resulting aurora in some parts of the world have been beautiful. Here’s a collection of recent images taken by Jason Arhns in Alaska. It seems the aurora is just blanketing not only the sky, but the landscape as well! See more below, as well as a video showing 23 of the 26 M- and X-class flares on the sun between Oct. 23 and Oct. 28, 2013, as captured by NASA’s Solar Dynamics Observatory. It also shows the coronal mass...

    Two EMP experts told Secrets that the EMP flashed through earth's typical orbit around the sun about two weeks before the planet got there. "The world escaped an EMP catastrophe," said Henry Cooper, who lead strategic arms negotiations with the Soviet Union under President Reagan, and who now heads High Frontier, a group pushing for missile defense. "There had been a near-miss about two weeks ago, a Carrington-class coronal mass ejection crossed the orbit of the Earth and basically just missed us," said Peter Vincent Pry, who served on the Congressional EMP Threat Commission from 2001-2008. He was referring to...

    According to researchers at EMPact America, an organization dedicated to studying and preparing for the possibility of large-scale electro magnetic pulse threats that can destroy our modern day electrical infrastructure, the earth came dangerously close to a serious destabilization event. A couple of weeks ago the sun emitted a massive CME (Coronal Mass Ejection) that, had it been earth-directed, would likely have wiped out critical portions of the world’s power grid and sent developed nations back to the stone age within a matter of seconds. ‘The world escaped an EMP catastrophe,’ Henry Cooper, who now heads High Frontier, a group...
