If a solar flare knocked out the grid around the globe it wouldn't take long for nuclear plants to shut down with uncontrollable catastrophic events to follow. Thats just one of the many scenarios that could result from our solar weather headed towards us in the near future!Space weather expert has ominous forecast
Mike Hapgood, who studies solar events, says the world isn't prepared for a truly damaging storm. And one could happen soon.

A stream of highly charged particles from the sun is headed straight toward Earth, threatening to plunge cities around the world into darkness and bring the global economy screeching to a halt.
This isn't the premise of the latest doomsday thriller. Massive solar storms have happened before — and another one is likely to occur soon, according to Mike Hapgood, a space weather scientist at the Rutherford Appleton Laboratory near Oxford, England.
Much of the planet's electronic equipment, as well as orbiting satellites, have been built to withstand these periodic geomagnetic storms. But the world is still not prepared for a truly damaging solar storm, Hapgood argues in a recent commentary published in the journal Nature.
Hapgood talked with The Times about the potential effects of such a storm and how the world should prepare for it.
What exactly is a solar storm?
I find that's hard to answer. The term "solar storm" has crept into our usage, but nobody has defined what it means. Whether a "solar storm" is happening on the sun or is referring to the effect on the Earth depends on who's talking.
I prefer "space weather," because it focuses our attention on the phenomena in space that travel from the sun to the Earth.
People often talk about solar flares and solar storms in the same breath. What's the difference?
Solar flares mainly emit X-rays — we also get radio waves from these things, and white light in the brightest of flares. They all travel at the same speed as light, so it takes eight minutes to arrive. There are some effects from flares, such as radio interference from the radio bursts.
But that's a pretty small-beer thing. The big thing is the geomagnetic storms [on Earth] that affect the power grid, and that's caused by the coronal mass ejections [from the sun].
Coronal mass ejections are caused when the magnetic field in the sun's atmosphere gets disrupted and then the plasma, the sun's hot ionized gas, erupts and send charged particles into space. Think of it like a hurricane — is it headed toward us or not headed toward us? If we're lucky, it misses us.
How are solar flares and coronal mass ejections related?
There's an association between flares and coronal mass ejections, but it's a relationship we don't quite understand scientifically. Sometimes the CME launches before the flare occurs, and vice versa.
What happens when those particles reach Earth?
There can be a whole range of effects. The classic one everyone quotes is the effect on the power grid. A big geomagnetic storm can essentially put extra electric currents into the grid. If it gets bad enough, you can have a complete failure of the power grid — it happened in Quebec back in 1989. If you've got that, then you've just got to get it back on again. But you could also damage the transformers, which would make it much harder to get the electric power back.
How else could people be affected?
You get big disturbances in the Earth's upper atmosphere — what we call the ionosphere — and that could be very disruptive to things like GPS [the network of global positioning system satellites]. Given the extent we use GPS in everyday life [including for cellphone networks, shipping safety and financial transaction records], that's a big issue.
The storms can also disrupt communications on transoceanic flights. Sometimes when that happens, they will either divert or cancel flights. So that would be the like the disruption we had in Europe from the volcano two years ago, where they had to close down airspace for safety reasons.
What went wrong in the 1989 storm?

Kenny the elite have prepared for it and they're not worried. They're going underground in their state of the art bunker complexes and they'll leave the rest of us for dead.

They're tired of our whining. Annoyed and freighted by the threat of our increasing awareness. They're going to kill us all. And start over. No one who is not them will be spared. A great war, Bio-virus and drones from their under ground bunkers. 80% of us must die. And they elites will emerge victorious, new Adams and Eves. No impediments to their dark desires to create a world in their image.

Nice story. Allow me to add my observation. Any effects of solar storms are cumulative with the effects of global warming. We don't have the option of choosing one of the other. We get the effects of one with the other. Sort of like if a lion knocks us down with severe injuries and leaves us, then the hyenas come to finish us off.

Perhaps the Maya and Aztecs knew something about solar cycles that we don't know. Notice the Sun sticking out its tongue on the Aztec Sun Stone calendar.....

Predicting Space Weather
by Amber Wilson-Daeschlein
SPACE WEATHER. To some, it might sound cosmically boring. To others, it is wonderfully celestial. To you, it should be something to pay attention to.Dr. Roger Dube, research professor at the Center for Imaging Science and director of RIT’s Space Exploration Program, is paying attention. He and the eight students working with him are using information gathered from telescopes, antennas and other sources to predict space weather patterns. By analyzing this data he hopes to be able to give advanced warning of anything that might affect us here on Earth.
Back in the mid 1800s, the use of electricity was slowly gaining popularity. The streets were lit by kerosene lanterns and more and more mail was being sent by the latest invention, the telegraph. The telegraph was the first electrical technology used by many people. Big cities were connected with telegraph lines allowing people to communicate much farther and more efficiently than was ever thought possible.
In 1858, a one-inch-diameter telegraph cable was laid across the Atlantic Ocean. Known as the trans-Atlantic cable, it spanned thousands of miles from North America to Europe, allowing the first ever overseas instant message to be sent in Morse code.
In September 1859, a British astronomer noticed a large group of sunspots followed by an intensely bright light emerging from the sun. Shortly after that, the sky erupted in a swirl of red and green colors so bright that miners in Colorado thought it was morning and got up to make breakfast.
These astonishing colors lasted for around three days, lighting up the sky and inducing large electrical currents in the ground. This caused the telegraph wires to conduct massive amounts of electricity, inducing sparks “so big they would set the [telegraph] paper tape on fire,” according to Dube, and the Transatlantic cable to be completely melted. Disconnecting the batteries had no effect since the current was coming from outer space; however, that was not discovered until later.
The phenomena that melted an inch-thick wire at the bottom of the ocean is called a solar storm. This happens when, according to Dube, a coronal mass ejection “launches a large and high speed charged quantity of matter into the interplanetary region and if that happens to strike a planet, it experiences space weather.”
Unlike the weather one might experience in Rochester — snow, rain and more snow — space weather has nothing to do with precipitation and water formation. This type of weather is an “electrical phenomenon” that causes particles to pass over the earth moving very quickly. Large amounts of current passing over a planet will induce charges in the ground.
A mild form of space weather will cause aurora borealis. However, when a more severe form of space weather hits the Earth, it becomes an electrical storm. “[These storms are] much, much worse than any lightning strike,” explains Dube.
When a severe enough storm is sent towards earth, it sends currents through every wire in the area it hits, causing varying ranges of electrical damage. Recently, an area in Canada was hit with a minor storm, and as a result six million people lost power for a day.
If a storm is much worse, it can melt wires and create sparks that would do irreversible damage. According to the National Academy of Scientists, if we got hit by a severe storm today, it would take an estimated 10 years for society to recover.
Ten years without electricity means we would have no central air and heating. It means that the local Wegmans would lose much of its food because the freezers and refrigerators to keep it cold would not work. It means that there would be no way to contact a loved one or friend because all cell and home phones are useless.
Dube’s research investigates how we could predict space weather patterns and be forewarned of impending storms, so we can be ready. It starts with the information received from telescopes in space whose sole job is to monitor the activity on the surface of the sun. These telescopes look at the sun’s coronasphere, or upper atmosphere, and track the solar flares.
Another way of gathering information is through antennas that are placed on buildings to “monitor what’s happening electrically in the upper atmosphere.” There are three antennas here at RIT. One is on top of Engineering Hall (ENG 17), which can be seen if you go to the glass walkway on the second floor and look up towards the top of the building. The other two are on top of the RIT Inn and Racquet Club.
Data from the telescopes and antennas, as well as historical data is then feed into a neural network computer algorithm that is “designed to mimic how the human mind learns,” with the advantage of being much faster than any person. This computer looks for patterns in the events that happen before a storm so that we can have an indicator of when a storm is about to strike.
Right now the correlation coefficient is 0.95; however, the computer doesn’t have any data from before the 1980s because the technology to measure space weather patterns had not been invented yet. “Right now that gives us about three days warning,” says Dube. “But that’s not good enough.” His goal for the future is to have the information about a week in advance so that society can adequately prepare. As of now, there are no plans for what may be similar to a post-apocalyptic world without electricity, or even a plan of what to do if we receive advanced warning of a solar storm. Solar flares operate on cycles of peaks that occur every eleven years. The next is predicted to occur in July 2013. While severe space weather isn’t necessarily anticipated, Dube says that it is important to be ready because of the unpredictable nature of electric storms. While space weather is a nerve-wracking reality, the work of Dube and other scientists can help prepare us for the worst.

Frying transformers that take months just too manufacture would insure many city's would be without power for months. No refrigeration, hospital emergency rooms without enough back up power fuel to operate more than a week. Total chaos and the end of what we have grown accustomed too!

And yet our government is doing nothing to be sure the grid will keep working, I know the 1% have already found shelter underground and talk of many going to NORAD on an underground train from the Denver International Airport ie DIA to NORAD, but I think some of that is conspiracy theory...
