VERY INTERESTING, Jim! But, it's doubtful that the US will be any more
prepared for something like this, than BP was for the Oil Spill.
IF it does happen let's just hope it isn't during a Summer with temps like we
have presently, or we'll have a mass of COOKED human beings - many deaths!

IT IS midnight on 22 September 2012 and the skies above Manhattan are filled with a flickering curtain of colorful light. Few New Yorkers have seen the aurora this far south but their fascination is short-lived. Within a few seconds, electric bulbs dim and flicker, then become unusually bright for a fleeting moment. Then all the lights in the state go out. Within 90 seconds, the entire eastern half of the US is without power.

A year later and millions of Americans are dead and the nation's infrastructure lies in tatters. The World Bank declares America a developing nation. Europe, Scandinavia, China and Japan are also struggling to recover from the same fateful event - a violent storm, 150 million kilometers away on the surface of the sun.
It sounds ridiculous. Surely the sun couldn't create so profound a disaster on Earth. Yet an extraordinary report funded by NASA and issued by the US National Academy of Sciences (NAS) in January this year claims it could do just that.
Over the last few decades, western civilizations have busily sown the seeds of their own destruction. Our modern way of life, with its reliance on technology, has unwittingly exposed us to an extraordinary danger: plasma balls spewed from the surface of the sun could wipe out our power grids, with catastrophic consequences.
The projections of just how catastrophic make chilling reading. "We're moving closer and closer to the edge of a possible disaster," says Daniel Baker, a space weather expert based at the University of Colorado in Boulder, and chair of the NAS committee responsible for the report.
It is hard to conceive of the sun wiping out a large amount of our hard-earned progress. Nevertheless, it is possible. The surface of the sun is a roiling mass of plasma - charged high-energy particles - some of which escape the surface and travel through space as the solar wind. From time to time, that wind carries a billion-tonne glob of plasma, a fireball known as a coronal mass ejection. (see "When hell comes to Earth"). If one should hit the Earth's magnetic shield, the result could be truly devastating.
The incursion of the plasma into our atmosphere causes rapid changes in the configuration of Earth's magnetic field which, in turn, induce currents in the long wires of the power grids. The grids were not built to handle this sort of direct current electricity. The greatest danger is at the step-up and step-down transformers used to convert power from its transport voltage to domestically useful voltage. The increased DC current creates strong magnetic fields that saturate a transformer's magnetic core. The result is runaway current in the transformer's copper wiring, which rapidly heats up and melts. This is exactly what happened in the Canadian province of Quebec in March 1989, and six million people spent 9 hours without electricity. But things could get much, much worse than that.
WORSE THAN KATRINA
The most serious space weather event in history happened in 1859. It is known as the Carrington event, after the British amateur astronomer Richard Carrington, who was the first to note its cause: "two patches of intensely bright and white light" emanating from a large group of sunspots. The Carrington event comprised eight days of severe space weather.
There were eyewitness accounts of stunning auroras, even at equatorial latitudes. The world's telegraph networks experienced severe disruptions, and Victorian magnetometers were driven off the scale.
Though a solar outburst could conceivably be more powerful, "we haven't found an example of anything worse than a Carrington event", says James Green, head of NASA's planetary division and an expert on the events of 1859. "From a scientific perspective, that would be the one that we'd want to survive." However, the prognosis from the NAS analysis is that, thanks to our technological prowess, many of us may not.
There are two problems to face. The first is the modern electricity grid, which is designed to operate at ever higher voltages over ever larger areas. Though this provides a more efficient way to run the electricity networks, minimising power losses and wastage through overproduction, it has made them much more vulnerable to space weather. The high-power grids act as particularly efficient antennas, channelling enormous direct currents into the power transformers.
The second problem is the grid's interdependence with the systems that support our lives: water and sewage treatment, supermarket delivery infrastructures, power station controls, financial markets and many others all rely on electricity. Put the two together, and it is clear that a repeat of the Carrington event could produce a catastrophe the likes of which the world has never seen. "It's just the opposite of how we usually think of natural disasters," says John Kappenman, a power industry analyst with the Metatech Corporation of Goleta, California, and an advisor to the NAS committee that produced the report. "Usually the less developed regions of the world are most vulnerable, not the highly sophisticated technological regions."
According to the NAS report, a severe space weather event in the US could induce ground currents that would knock out 300 key transformers within about 90 seconds, cutting off the power for more than 130 million people (see map). From that moment, the clock is ticking for America.
First to go - immediately for some people - is drinkable water. Anyone living in a high-rise apartment, where water has to be pumped to reach them, would be cut off straight away. For the rest, drinking water will still come through the taps for maybe half a day. With no electricity to pump water from reservoirs, there is no more after that.
There is simply no electrically powered transport: no trains, underground or overground. Our just-in-time culture for delivery networks may represent the pinnacle of efficiency, but it means that supermarket shelves would empty very quickly - delivery trucks could only keep running until their tanks ran out of fuel, and there is no electricity to pump any more from the underground tanks at filling stations.
Back-up generators would run at pivotal sites - but only until their fuel ran out. For hospitals, that would mean about 72 hours of running a bare-bones, essential care only, service. After that, no more modern healthcare.
72 HOURS OF HEALTHCARE REMAINING
The truly shocking finding is that this whole situation would not improve for months, maybe years: melted transformer hubs cannot be repaired, only replaced. "From the surveys I've done, you might have a few spare transformers around, but installing a new one takes a well-trained crew a week or more," says Kappenman. "A major electrical utility might have one suitably trained crew, maybe two."
Within a month, then, the handful of spare transformers would be used up. The rest will have to be built to order, something that can take up to 12 months.
Even when some systems are capable of receiving power again, there is no guarantee there will be any to deliver. Almost all natural gas and fuel pipelines require electricity to operate. Coal-fired power stations usually keep reserves to last 30 days, but with no transport systems running to bring more fuel, there will be no electricity in the second month.
30 days of coal left
Nuclear power stations wouldn't fare much better. They are programmed to shut down in the event of serious grid problems and are not allowed to restart until the power grid is up and running.
With no power for heating, cooling or refrigeration systems, people could begin to die within days. There is immediate danger for those who rely on medication. Lose power to New Jersey, for instance, and you have lost a major center of production of pharmaceuticals for the entire US. Perishable medications such as insulin will soon be in short supply. "In the US alone there are a million people with diabetes," Kappenman says. "Shut down production, distribution and storage and you put all those lives at risk in very short order."
Help is not coming any time soon, either. If it is dark from the eastern seaboard to Chicago, some affected areas are hundreds, maybe thousands of miles away from anyone who might help. And those willing to help are likely to be ill-equipped to deal with the sheer scale of the disaster. "If a Carrington event happened now, it would be like a hurricane Katrina, but 10 times worse," says Paul Kintner, a plasma physicist at Cornell University in Ithaca, New York.
In reality, it would be much worse than that. Hurricane Katrina's societal and economic impact has been measured at $81 billion to $125 billion. According to the NAS report, the impact of what it terms a "severe geomagnetic storm scenario" could be as high as $2 trillion. And that's just the first year after the storm. The NAS puts the recovery time at four to 10 years. It is questionable whether the US would ever bounce back.
4-10 YEARS TO RECOVER
"I don't think the NAS report is scaremongering," says Mike Hapgood, who chairs the European Space Agency's space weather team. Green agrees. "Scientists are conservative by nature and this group is really thoughtful," he says. "This is a fair and balanced report."
Such nightmare scenarios are not restricted to North America. High latitude nations such as Sweden and Norway have been aware for a while that, while regular views of the aurora are pretty, they are also reminders of an ever-present threat to their electricity grids. However, the trend towards installing extremely high voltage grids means that lower latitude countries are also at risk. For example, China is on the way to implementing a 1000-kilovolt electrical grid, twice the voltage of the US grid. This would be a superb conduit for space weather-induced disaster because the grid's efficiency to act as an antenna rises as the voltage between the grid and the ground increases. "China is going to discover at some point that they have a problem," Kappenman says.
Neither is Europe sufficiently prepared. Responsibility for dealing with space weather issues is "very fragmented" in Europe, says Hapgood.
Europe's electricity grids, on the other hand, are highly interconnected and extremely vulnerable to cascading failures. In 2006, the routine switch-off of a small part of Germany's grid - to let a ship pass safely under high-voltage cables - caused a cascade power failure across western Europe. In France alone, five million people were left without electricity for two hours. "These systems are so complicated we don't fully understand the effects of twiddling at one place," Hapgood says. "Most of the time it's alright, but occasionally it will get you."
The good news is that, given enough warning, the utility companies can take precautions, such as adjusting voltages and loads, and restricting transfers of energy so that sudden spikes in current don't cause cascade failures. There is still more bad news, however. Our early warning system is becoming more unreliable by the day.
By far the most important indicator of incoming space weather is NASA's Advanced Composition Explorer (ACE). The probe, launched in 1997, has a solar orbit that keeps it directly between the sun and Earth. Its uninterrupted view of the sun means it gives us continuous reports on the direction and velocity of the solar wind and other streams of charged particles that flow past its sensors. ACE can provide between 15 and 45 minutes' warning of any incoming geomagnetic storms. The power companies need about 15 minutes to prepare their systems for a critical event, so that would seem passable.
15 MINUTES' WARNING
However, observations of the sun and magnetometer readings during the Carrington event shows that the coronal mass ejection was travelling so fast it took less than 15 minutes to get from where ACE is positioned to Earth. "It arrived faster than we can do anything," Hapgood says.
There is another problem. ACE is 11 years old, and operating well beyond its planned lifespan. The onboard detectors are not as sensitive as they used to be, and there is no telling when they will finally give up the ghost. Furthermore, its sensors become saturated in the event of a really powerful solar flare. "It was built to look at average conditions rather than extremes," Baker says.
He was part of a space weather commission that three years ago warned about the problems of relying on ACE. "It's been on my mind for a long time," he says. "To not have a spare, or a strategy to replace it if and when it should fail, is rather foolish."
There is no replacement for ACE due any time soon. Other solar observation satellites, such as the Solar and Heliospheric Observatory (SOHO) can provide some warning, but with less detailed information and - crucially - much later. "It's quite hard to assess what the impact of losing ACE will be," Hapgood says. "We will largely lose the early warning capability."
The world will, most probably, yawn at the prospect of a devastating solar storm until it happens. Kintner says his students show a "deep indifference" when he lectures on the impact of space weather. But if policy-makers show a similar indifference in the face of the latest NAS report, it could cost tens of millions of lives, Kappenman reckons. "It could conceivably be the worst natural disaster possible," he says.
The report outlines the worst case scenario for the US. The "perfect storm" is most likely on a spring or autumn night in a year of heightened solar activity - something like 2012. Around the equinoxes, the orientation of the Earth's field to the sun makes us particularly vulnerable to a plasma strike.
What's more, at these times of year, electricity demand is relatively low because no one needs too much heating or air conditioning. With only a handful of the US grid's power stations running, the system relies on computer algorithms shunting large amounts of power around the grid and this leaves the network highly vulnerable to sudden spikes.
If ACE has failed by then, or a plasma ball flies at us too fast for any warning from ACE to reach us, the consequences could be staggering. "A really large storm could be a planetary disaster," Kappenman says.
So what should be done? No one knows yet - the report is meant to spark that conversation. Baker is worried, though, that the odds are stacked against that conversation really getting started. As the NAS report notes, it is terribly difficult to inspire people to prepare for a potential crisis that has never happened before and may not happen for decades to come. "It takes a lot of effort to educate policy-makers, and that is especially true with these low-frequency events," he says.
We should learn the lessons of hurricane Katrina, though, and realize that "unlikely" doesn't mean "won't happen". Especially when the stakes are so high. The fact is, it could come in the next three or four years - and with devastating effects. "The Carrington event happened during a mediocre, ho-hum solar cycle," Kintner says. "It came out of nowhere, so we just don't know when something like that is going to happen again."

Just recently there was a bill in congress that would have required power companies to protect their equipment from these flares or the EMP from a terrorist nuclear weapon. It was defeated. As I recall the reason was it would cost too much!
Already feels like solar flares here! 99* due tomorrow, where normally temp
would be mid 80's. Horribly hot/humid all of August and due to continue rest
of the month, as was 2nd half of July. Plus, no rain here except for 5
minute light showers for all of August so far.
I do keep 1/2 gal milk jugs of pure water by chairs and bed, in each room &
5 extra in kitchen which I rotate to keep fresh.
This is really a Killer Summer around here - Ohio/N. Ky area.
We are extra cool In Idaho. Parts of California too and they are concerned about crops ripening sufficiently due to 50 degree temps. 42 degrees for us this am.... and so much rain the past few days. Should be near you by now earlybird.
And here is a report on a solar flare that happened in 2004
Sun's Massive Explosion Upgraded
the X45 class event was more than twice as big as the previous record flare
March 17, 2004
By Dr David Whitehouse
BBC News Online science editor
The massive solar flare that erupted from the Sun last November was far bigger than scientists first thought.
Image: The flare overloaded detectors (SOHO)
At the time, satellite detectors were unable to record its true size because they were blinded by its radiation.
But University of Otago physicists say they have now estimated the probable scale of the huge explosion by studying how X-rays hit the Earth's atmosphere.
They tell Geophysical Research Letters the X45 class event was more than twice as big as the previous record flare.
Fortunately, the Earth did not take a direct hit from this immense blast of radiation and matter.
Had it done so, several orbiting satellites would almost certainly have been damaged and there could have been considerable disruption of radio communications and power grids on the planet's surface.
THE BIG ONE
Image: The gas cloud starts on its way (Solar Heliospheric Observatory image)
Last October and November, the Sun underwent an extraordinary surge in activity, producing a series of big flares from the most active sunspot region ever seen.
Day after day, gas was being explosively heated to millions of degrees, sending radiation and billions of tonnes of charged particles streaming into space.
But it was on 4 November, as Active Region 486 was being carried out of sight around the Sun's western limb by solar rotation, that the most extraordinary flare let rip.
Between 1929 and 1950 GMT, the enormous explosion sent an intense burst of radiation towards the Earth.
SOLAR FLARE CLASSES
Flares classified by brightness at X-ray wavelengths
X-class is biggest; can trigger radio blackouts on Earth
M-class is medium-sized; radio interference at polar regions
C-class is smallest; few noticeable effects on Earth
Even before the storm had peaked, X-rays had overloaded the detectors on solar-monitoring satellites, in particular those on the Geostationary Operational Environmental Satellites, which usually provide data allowing scientists to estimate the size of such events.
Later study suggested the flare was an X28.
RIGHT PLACE AND TIME
The biggest previous solar flares on record were rated X20, on 2 April 2001 and 16 August 1989. So 4 November's explosion certainly set a new mark. But only now do scientists understand the probable true power of the event.
The New Zealand researchers in Otago looked at the effect the flare's radiation had on the Earth's upper atmosphere and used that to judge its strength.
"So when this event overloaded the satellite detectors, we were in a unique position to make this measurement," they said.
THE IONOSPHERE
Refers to region of Earth's upper atmosphere
Normally extends 70 to 400 km above the surface
Atmosphere location where solar radiation can affect transmissions of radio waves
Detailing their work in their journal paper, the team report that at the time of the big solar explosion they were probing the ionosphere with radio waves as part of a long-term research programme.
They noticed that X-rays from the flare changed the properties of the ionosphere, an effect that has been observed many times before.
MASSIVE BOMBARDMENT
The changes the Otago researchers saw allowed them to produce a new estimate of the flare's intensity, increasing its rating from X28 to X45.
"This makes it more than twice as large as any previously recorded flare," said Associate Professor Neil Thomson.
Luckily the radiation from the flare only struck a glancing blow to the Earth.
"If the accompanying particle and magnetic storm had been aimed at the Earth, the damage to some satellites and electrical networks could have been considerable," said Thomson.
The New Zealanders say their calculations show the flare's X-ray radiation bombarding the atmosphere was equivalent to that of 5,000 suns, though none of it reached the Earth's surface, they stress.
"Given that any future flares are unlikely to be large enough to overload the ionosphere, we believe that our new method has great advantages in determining their size in the event of satellite detector overloads," said Thompson.
The most likely senario for earth changes related to the 2012 prophecies is the combination in the current change in the magnetic field of the earth and solar storms.
OK, things are amping up now. We had a solar flare this morning 3 times larger than the one in Feb. 2011. and the largestest yet in this new solar cycle we have entered into. Haven't heard any reports yet on effects on technology. It will much depend on whether the impact is over the ocean and what satellites it may hit.
X6.9 Solar Flare!
A strong burst of radiation, a flare, was measured by the GOES satellite. The flare was also seen as a light flash in PROBA2/SWAP and SDO/AIA images. Solar radiation reaches the Earth after 8 minutes. This flare is up to now the strongest flare of the current solar cycle.
Shortly after the peak of the flare, the proton flux near Earth increased. GOES is also capable of measuring these energetic electrical particles. The Sun throws a whole bunch of these particles into space, more then usual. The proton flux passed the storm threshold. The storm level is not dramatic.
A plasma cloud left the Sun at the moment of the event. It is now travelling through space at a speed of more then 1000 km/s. At a speed of 1000 km/s and no deceleration, a cloud bridges the distance between the Sun and the Earth in 1 day and 17 hours. The plasma cloud is not directed straight to Earth. But a glancing blow is possible and can cause a geomagnetic storm.
Possible consequences on the day side of the Earth associated with the radiation burst:
radio communication can be interrupted – satellites orbitting just above the Earth atmosphere can feel a drag force – navigation systems based on satellites and signal passage through the ionosphere can be disturbed. Possible consequences associated with the proton event:
Additional radiation at the Earth poles and in space (ISS is vunerable) – Radio communication disruption at the poles
Additional effects are possible at arrival of the plasma cloud
Thanks Arrow. Thanks for reminding me to keep up with this stuff. I've had too many diversions recently. Also, now that you have presented us with that Watchers website, I'll have a more central location. https://thewatchers.adorraeli.com/
And why is this important? Because something striped the atmosphere from Mars. The same could happen to us. Not that we can do anything about it. Same for an asteroid strike. I already feel that I'm in a solar flare or a global warming victim. Over 30 days of triple digit temps in Texas.
I heard about Texas! Im glad Im not in Dallas anymore, and this is another reason.
Weather here has been unusually cold for Idaho. For the whole northwest actually, and so much rain this month that is not common at all. We keep trying to get our roof on and as soon as they get up there it rains so I tell them to quite going on the roof cause their making it rain.
