the united States. – -, we accumulate news worrying about the Sun and solar storms, these violent explosions that take place on its surface that propel the space huge projectiles of plasma magnetized. We have read that Obama ordered to the country to prepare for a disaster, that even in Germany the government recommends to its citizens to stockpile food and water; and now comes a new story about a solar blast that has caused a bath of cosmic rays in the Earth. On the other hand, in our Facebook and Whatsapp is coming back to the famous hoax of which NASA predicts 15 days of darkness, a lie viral every once in a while he rises stubbornly which zombie doesn’t end of dying. From the apocalypse of the M ayan prophecies about the end of the world in 2012, we had not seen an uptick as frantic news distressing related to the Sun. The scientists who work in this topic we are continuously queries from concerned citizens, because, as says the proverb, “when the river sounds, is that water bears”. The more suspicious have come to the conclusion that the authorities know something we hide, something imminent is coming. After all, Obama has given the order to prepare.
What is true is that yes it is coming an event imminent and potentially dangerous for the planet. This is the election to the presidency of the united States. The Obama Administration takes a lot of time developing a strategy to respond to a possible adverse situation caused by a large solar event. This strategy arises from the budget office and consists of a series of measures, financing lines and roadmaps for the different national agencies.
it Is estimated that a large solar storm comparable to the “event Carrington”, that struck the Earth in 1859, would cause damage to our tissue technology worth several billion dollars. Solar storms are not disasters apocalípiticas, in the sense of sowing death and destruction everywhere. Keep in mind that have been occurred throughout the life, since before man stepped on the Earth. The difference with previous situations is that our technology is itself vulnerable to these phenomena of electromagnetic nature and each time we are more dependent on it.

that Is to say, the event for which it is prepared the Obama Administration is not that of a great human tragedy, but a true financial crisis on a global scale comparable to that caused by the subprime mortgages in 2008. We cannot know in advance when it will occur the next event type Carrington but scientific studies suggest that the probability is approximately 10% every decade.
why, then, orders Obama to your country that you prepare right now? What is it that you have seen? In reality, nothing. Valentin Martinez, director of the National Solar Observatory of the united states,” clarified in statements to” señalyruido.com”. It is a misunderstanding due to a translation too literally. What makes Obama is what they usually do american presidents at the end of his mandate: to rush, to be embodied in laws to those initiatives in which they have been working for the legislature. In this way, is transferred to the following president the obligation to comply (or repeal) of these resolutions.
this action, in legal jargon american, it’s called “executive order”, which many translate literally into our language as “issue an executive order” but perhaps it would be more faithful to translate by “pass a law”. The difference is very large because it sounds a lot more worrisome and imminent say “Obama ordered to prepare” to “Obama approves a bill to prepare”. Therefore, there is not that you read in the news that the us authorities have news of some imminent catastrophe, but the very successful initiative of a country that wants to be prepared for something that will happen sooner or later. Surely not tomorrow or past, but almost certainly in the next 50 or 100 years. Perhaps what is surprising is that not all of us are others doing the same.
A new event Carrington
A new event type Carrington that took place today could have catastrophic consequences (or perhaps not) but we do not know exactly to what extent. We don’t know which satellites would be affected or to what extent, what would happen to the electrical supply network, so interconnected in some parts of the world that could lead to falls in the chain, potential failures of the GPS network that affect processes as diverse as the navigation or the stock exchange transactions, etc
There are a few studies and zero experience with extreme events. You may not pass great thing, as when the famous bug of the year 2000. Or you can give consequences that are banal, as to miss the Champions league final, or that no longer work mobile for a few days. Or perhaps we are in a protracted situation for weeks, even months, with cuts of connection to the internet, collapse of the air and surface transportation, shortages of goods and chaos in the cities.
Returning to the case of the USA, there have been considered at a series of satellites that are of strategic importance for national security. These satellites are duplicated, so that for every one that there is in orbit, there is an identical copy stored in a warehouse, completely ready to be thrown at any time. The air force has an emergency programme that would allow them to launch all these instruments and replace the network within a maximum period of one week. Clearly, the military is taking this matter very seriously. And civil society also it is an understanding, even if you do it more slowly.
We have much to learn but we must not be alarmist. What is certain is that there is nothing strange or unusual in the activity of the Sun in the last few weeks. Also in the magnetic shield of the Earth. The magnetosphere is a magnetic field that envelops our planet and traps high-energy particles produced by a solar storm. It also catches and deflects the cosmic rays, natural radiation, also in the form of high-energy particles that bombard us continuously from the Universe.
The cosmic rays are generated in different scenarios, such as in the vicinity of black holes or in the explosions of stars known as supernovae. A team of indian researchers and the japanese, working with an experiment to detect cosmic rays in India, have published these days the results of scientific research very interesting.
In your article demonstrate that, during a period of something over two hours, the Earth was exposed to a bombing more than usual of cosmic rays during a solar storm of magnitude moderate that struck our planet in June of 2015. According to this work, the solar storm hit the magnetosphere, comprimiéndola and giving rise to events of magnetic reconnection, which resulted in a temporary break of this protection that sneaked in these cosmic rays.
The news has gone out these days, contributing to that feeling of concern about the behavior of the Sun, but we have to bear in mind that the event referred to in the article occurred more than a year ago. What is posted now is the result of the research. Probably this kind of situations, in the weakening of the magnetosphere during a big solar storm, occur with relative frequency.
Low solar activity
the odd Thing is that, if we look at the evolution of the solar activity during the last decades, we find that we are in a period of activity unusually low and apparently on a downward trend. Saku Tsuneta, vice president of the Space Agency Japan (JAXA), said in Abc.is that the Sun is entering into a new Minimum of Maunder, a kind of hibernation of 70 years, who suffered in the SEVENTEENTH century, and which probably gave rise to a colder climate on Earth.
In some forums of discussion about these topics, I have heard the criticism that the scientists have no idea of if there is to be concerned about the sun’s activity or lack of activity. Personally, I think that what we have to do is worry about better understand the Sun and its impact on our planet and our technology. The ignorance is just as damaging as the fear-mongering apocalyptic. As a society we need to move forward in the knowledge and at the same time be prepared for situations that may occur.
As we assume that we live on a planet that is active, with its earthquakes, eruptions and other manifestations, we have to also understand that we live with a star active, their whims, their caprices and their leaders, at times, even violent.
