Solar flare top class The third according to the Institute of Applied Geophysics Academician EK Fedorov Russian Hydrometeorological Center X-ray flash upper class (power X) occurred this week in the sun.
The outbreak occurred October 29, 2013 at 21:54 GMT, it was the source of the active region 1875, which is located on the solar disk from the western region and will soon go away on a hidden side of the planet with our bodies. This situation is not considered a geo-effective, at which leakage of plasma from the sun can reach our planet, causing geomagnetic disturbances. Nevertheless, it is possible and a sharp increase in the flux of protons.
October 25, 2013 another active region 1882 has produced two powerful X-class flare and a series of less powerful M-class flares, which were not observed in the sun for six months - from May 2013.
Solar flares are accompanied by emission of solar plasma, which, if reach the Earth, can trigger magnetic storms on it.

The dependence of space weather from sunny climate Luke Barnard of the University of Reading (UK) and his colleagues have shown that the space-age history of mankind has coincided with a period of unusually high solar activity, nicknamed the great high.
Isotopes in ice sheets and tree rings suggest that such great solar maxima in the last 9,300 years was 24. The current is coming to an end, that is, indicators of the magnetic field of the sun will soon fall, will reduce the number of sunspots, coronal mass ejections will occur less frequently.
Coronal mass ejection, the SOHO spacecraft photographed June 7, 2011.
All of this will affect the cosmic radiation, which is very interested scientists and engineers, because it represents a threat to a variety of artificial systems (eg, satellites), as well as the potential to cause harm to astronauts and (to a lesser extent) the crew is particularly high flying aircraft.
The main sources of cosmic rays - galactic cosmic rays (continuous flow of high-energy particles reaching us from outside the solar system) and solar energetic particles that are accelerated thanks to the solar eruptions. The amount of radiation in the near-Earth space from these two sources is partly controlled by the magnetic field of the Sun.
There are theoretical predictions, supported by the observation that the decrease in the average magnetic field luminaries will lead to an increase in the number of galactic cosmic rays (GCR), reaching the vicinity of the Earth. Also predicted that, although the decline in solar activity will lead to less frequent emission of high energy particles, flash will be stronger and will cause more harm.
Meanwhile, the current space vehicles and aircraft are protected only by the level of radiation that was observed during the space age.
Comparing the current grand maximum of 24 previous, Mr. Barnard predicts an 8-percent probability that the solar activity will fall to very low levels, comparable to the so-called Maunder minimum XVII., During which it was observed a few sunspots. In this case, the GCR flux is likely to increase by 2.5 times compared to the present value, and large emissions of high-energy particles will occur about twice a century instead of the current five.
It is much more likely that in the next 40 years, solar activity will decline by about half, and in this case, the flow GCR increase 1.5 times, and large emissions of high-energy particles will occur eight times in a century. As a result, the near-Earth space radiation is likely to become more dangerous.
The results of the study were presented at the British-German national astronomical conference in Manchester.
in the wake of Computerra-Online and the Royal Astronomical Society.
Solar Earthquakes and Blackout Evidence

(CNN)-U.S. politics had its "Super Tuesday" yesterday, and so did the sun, says Joseph Kunches from NOAA's Space Weather Prediction Center in Boulder, Colorado.
That's because the sun had two solar flares associated with two coronal mass ejections. Coronal mass ejections involve massive amounts of energy and charged particles shooting out of the sun, and can cause problems if directed at Earth, as was the case over the last couple of days.
This event may stir up a geomagnetic storm, and lead to disruptions to high-frequency radio communications, global positioning systems and power grids, NASA's Goddard Space Flight Center said Wednesday. The peak of the storm is expected to hit Thursday morning; it may gradually diminish by Friday morning.
One of these coronal mass ejections is the strongest since December 2006, NOAA said. The equivalent of 10 billion tons of highly charged particles are hurtling at a rate of 3 million to 4 million miles an hour toward Earth. NASA says the leading edge of this coronal mass ejection will hit Earth at 1:25 a.m. E.T. (give or take seven hours).
The sun is currently in a cycle of increased sun spots. This is part of an 11-year cycle that is expected to peak over the next year. The magnetic field in a sunspot stores energy that is released in solar flares. These flares are intense bursts of radiation that get ejected into space.
NOAA measures various aspects of the ejections that occur. Four main components define solar activity: solar flares, coronal mass ejections, high-speed solar wind and solar energetic particles.
As an event occurs, some of the particles reach Earth almost immediately. These highly charged particles are more of a threat to spacecraft and astronauts than to us on the planet's surface. The bulk plasma from the coronal mass ejection can take between 30 and 72 hours to reach the earth. This can cause interruptions to power grids, GPS systems, and some flights that are near the poles.
The one positive outcome is the brilliant auroras (Northern and Southern Lights). These occur as the particles from the ejection interact with the Earth's magnetic field, creating colorful displays.
NOAA has a chart that classifies these solar storms. This latest coronal mass ejection is forecast to rate as a "strong G3" geomagnetic storm, a measure of the disturbances in the geomagnetic field that helps protect the Earth from dangerous particles, and a "severe S4" solar radiation storm which is a measure of radiation that occurs when the numbers of energetic particles increases.
The Space Prediction Center expects that we are in a favorable pattern for at least the next week to potentially bring more solar storms to the earth. What is not known is the magnitude of future events. What is expected is quite a show from the Northern Lights Wednesday night and Thursday night, which may be visible as far south as Michigan and Illinois.

October 2013 Breaking News Extreme Solar Flares EMP scheduled to hit earth (EMP) Electromagnetic pulse - Last days final hour news prophecy update
The general consensus in the community of scientists and military who deal with EMP on a day to day basis, is that a solar or military EMP is not a question of if, it is only a question of when. NASA/NOAA published a report in 2009 predicting a significant increase in solar activity peaking in 2013. An EMP takes out electric grids taking out major cities very dangerous for mankind,

Dr Richard Fisher, the director of Nasa's Heliophysics division, is very clear in the quotes, and our reporter, Andrew Hough, was very careful to check his facts with Dr Fisher before publishing. It sounds like a lot of serious people think that this is a real danger.
Apparently the concern is in 2013, the sun will reach a stage of its cycle when these large events are more likely. This might strike you as a bit strange, as you've probably heard (as have I) that the sun has been especially active for the last half-century or so and is expected to die down in the next couple of years -- I spoke to Marcus Chown, the physicist and author of We Need to Talk about Kelvin, who said "Solar activity has been abnormally high for the past 50 years, but the extremely feeble start to the latest 11-year cycle suggests this activity is coming to an end and things are going to be quiet on the Sun for quite a few years." Dr Ruth Bamford, a plasma physicist at the Rutherford-Appleton Laboratory, agrees: "The sun has been particularly quiet for the last few years in a protracted solar minimum. It has just woken up, as it were, and started its usual 11-year cycle a bit later than most."
So what's going on? Well, something similar has happened before. In 1859 a huge solar storm burned out telegraph wires across Europe and the United States. Dr Stuart Clark has written a book, The Sun Kings, about when that happened. He says that the "Carrington flare", as it was known, "smothered two-thirds of the Earth's skies in a blood-red aurora a night later, and crippled all of global navigation and global communication, such as it was at that time. Compasses span uselessly and the telegraph network went down as phantom electricity surged through the wire."
The sun had indeed been running at a record high for the latter half of the 20th century, and has now died down to its lowest level for a century. But Dr Clark warns that "average levels of solar activity has fallen does not mean that the Sun is immune from large flares or even giant ones. Low average levels of activity may even promote the giant flares.
"Perhaps like earthquakes, when there are constant flares/tremors the energy is dissipated evenly over long periods of time. But in periods of quiet, that energy can build up and then suddenly be released in a giant event. This remains speculation, however."
2013 is when the next peak in the sun's cycle of activity is expected, and while we cannot predict individual flares, Dr Clark says that the largest flares are often shortly after the peak.
Of course, if a proper "Carrington event" happens again, it has the potential to be far more problematic now than in 1859 when electric communication was barely in its infancy. Dr Clark says "There is absolutely no reason to believe that we are heading for solar armageddon in 2013, but sooner or later we should expect there to be another Carrington event and that is what these scientists [at NASA] are trying to prevent. Legislation in the US has just passed Congress to help harden the grid against solar flares."
So -- it's a real thing, and we should be concerned. But preventive measures can be taken -- satellites can be sent offline during big flares, power grids and communication networks can be shielded against electromagnetic radiation and so on. As Dr Bamford says: "The extreme events like the 1859 Carrington Event are 1-in-100-year probabilities, about the same probability as a storm of the level of Katrina hitting New Orleans -- and New Orleans did not build their defences to withstand the extreme-magnitude. The Katrina catastrophy is small compared to getting hit with solar flares.
The third according to the Institute of Applied Geophysics Academician EK Fedorov Russian Hydrometeorological Center X-ray flash upper class (power X) occurred this week in the sun.
