    As a first step toward determining the socioeconomic impacts of extreme space weather events and addressing the questions of space weather risk assessment and management, a public workshop was held in May 2008. The workshop brought together representatives of industry, the government, and academia to consider both direct and collateral effects of severe space weather events, the current state of the space weather services infrastructure in the United States, the needs of users of space weather data and services, and the ramifications of future technological developments for contemporary society's vulnerability to space weather. The workshop concluded with a discussion of un- or underexplored topics that would yield the greatest benefits in space weather risk management.

    Earlier this year, the US space agency Nasa warned that a peak in the sun's magnetic energy cycle and the number of sun spots or flares around 2013 could generate huge radiation levels.

    The resulting solar storm could cause a geomagnetic storm on Earth, knocking out electricity grids around the world for hours, days, or even months, bringing much of normal life grinding to a halt.

    FTER 10 years of comparative slumber, the sun is waking up - and it's got astronomers on full alert.

    This week several US media outlets reported that NASA was warning the massive flare that caused spectacular light shows on Earth earlier this month was just a precursor to a massive solar storm building that had the potential to wipe out the entire planet's power grid.

    NASA has since rebutted those reports, saying it could come "100 years away or just 100 days", but an Australian astronomer says the space community is betting on the sooner scenario rather than the latter.

    Despite its rebuttal, NASA's been watching out for this storm since 2006 and reports from the US this week claim the storms could hit on that most Hollywood of disaster dates - 2012.

    Similar storms back in 1859 and 1921 caused worldwide chaos, wiping out telegraph wires on a massive scale.

    The 2012 storm has the potential to be even more disruptive.

    "The general consensus among general astronomers (and certainly solar astronomers) is that this coming Solar maximum (2012 but possibly later into 2013) will be the most violent in 100 years," astronomy lecturer and columnist Dave Reneke said.

    "A bold statement and one taken seriously by those it will affect most, namely airline companies, communications companies and anyone working with modern GPS systems.
    "They can even trip circuit breakers and knock out orbiting satellites, as has already been done this year."

    Regardless, the point astronomers are making is it doesn't matter if the next Solar Max isn't the worst in history, or even as bad as the 1859 storms.
    It's the fact that there hasn't been one since the mid-80s. Commodore had just launched the Amiga and the only digital storm making the news was Tetris.
    No one really knows what effect the 2012-2013 Solar Max will have on today's digital-reliant society.

    Dr Richard Fisher, director of NASA’s Heliophysics division, told Mr Reneke the super storm would hit like "a bolt of lightning”, causing catastrophic consequences for the world’s health, emergency services and national security unless precautions are taken.

    US government officials earlier this year took part in a "tabletop exercise" in Boulder, Colorado, to map out what might happen if the Earth was hit with a storm as intense as the 1859 and 1921 storms.

    The 1859 storm was of a similar size to that predicted by NASA to hit within the next three years – one of decreased activity, but more powerful eruptions.
    NASA said that a recent report by the National Academy of Sciences found that if a similar storm occurred today, it could cause “$1 to 2 trillion in damages to society's high-tech infrastructure and require four to 10 years for complete recovery”.
    Staff at the Space Weather Prediction Center in Colorado, which hosted the exercise, said with our reliance on satellite technology, such an event could hit the Earth with the magnitude of a global hurricane or earthquake.

    The reason for the concern comes as the sun enters a phase known as Solar Cycle 24.
    All the alarming news building around the event is being fuelled by two things.

    The first is a book by disaster expert Lawrence E. Joseph, Guilty of Apocalypse: The Case Against 2012, in which he claims the "Hurricane Katrina for the Earth" may cause unprecedented planetwide upheaval.

    The second is a theory that claims sunspots travel through the sun on a "conveyor belt" similar to the Great Ocean Conveyor Belt which controls weather on Earth.
    The belt carries magnetic fields through the sun. When they hit the surface, they explode as sunspots.

    Weakened, they then travel back through the sun's core to recharge.

    It all happens on a rough 40-50-year cycle, according to solar physicist David Hathaway of the National Space Science and Technology Center in the US.
    He says when the belt speeds up, lots of magnetic fields are collected, which points to more intense future activity.
    "The belt was turning fast in 1986-1996," Prof Hathaway said.

    "Old magnetic fields swept up then should reappear as big sunspots in 2010-2011."
    Most experts agree, although those who put the date of Solar Max in 2012 are getting the most press.
    They claim satellites will be aged by 50 years, rendering GPS even more useless than ever, and the blast will have the equivalent energy of 100 million hydrogen bombs.
    “We know it is coming but we don’t know how bad it is going to be,” Dr Fisher told Mr Reneke in the most recent issue of Australasian Science.
    “Systems will just not work. The flares change the magnetic field on the Earth and it’s rapid, just like a lightning bolt.
    "That’s the solar effect.”

    Space storm alert: 90 seconds from catastrophe
    IT IS midnight on 22 September 2012 and the skies above Manhattan are filled with a flickering curtain of colourful 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 kilometres away on the surface of the sun.

    It sounds ridiculous. Surely the sun couldn't create so profound a ...

    A GIANT explosion of energy from the Sun could paralyse Earth in just three years' time, scientists warned yesterday.

    [http://www.thesun.co.uk/sol/homepage/news/3145874/Solar-flare-to-paralyse-Earth-in-2013.html

    They fear a huge solar flare is due to erupt in 2013 - causing blackouts and global chaos.

    The once-in-a-century disaster could see power grids crash, communication systems collapse, planes grounded, food supplies hit and the internet shut down.

    Everything from home freezers to car sat navs would be affected.

    The disaster could mirror the Great Solar Flare of 1859.

    In the movie 2012, starring John Cusack, a solar flare causes global temperatures to soar. The planet is then battered by tsunamis and earthquakes, threatening mankind.

    Yesterday's conference also heard that a hostile power could cause a similar effect by exploding a nuclear weapon in space.

    Dr Fox added: "While we all benefit from scientific advances, so we also create vulnerabilities that can be exploited by our enemies.

    "However advanced we become, the chain of our security is only as strong as its weakest link."

    Last night the electric security council discussed a plan of action.

    And former US government defence adviser Dr Avi Schnurr warned: "A geomagnetic storm could shatter nations all over the earth. We cannot wait for disaster to spur us to action."

    Solar flares: everything you need to know
    http://www.telegraph.co.uk/science/space/8012997/Solar-flares-everything-you-need-to-know.html
    Scientist are warning that an explosion of solar flares could disrupt communications on Earth at any time. But what causes these sudden bursts of light and how do they affect us?

    What is a solar flare?
    A solar flare is a large explosion of magnetic energy in the Sun’s atmosphere which causes an intense burst of increased brightness. They cannot be detected by the naked eye from the surface of the earth but can be observed through telescopes, space x-rays and thermal imaging equipment.

    The amount of energy released by a flare can be equivalent to millions of 100-megaton hydrogen bombs exploding at the same time – ten million times greater than that released by a volcanic eruption.

    Often lasting just a few minutes, solar flares heat material to many millions of degrees and produce a burst of radiation across the electromagnetic spectrum, including from radio waves to x-rays and gamma rays.

    When, why and where do they occur?
    A flare occurs when magnetic energy that has built up in the solar atmosphere is suddenly released - mostly in the active regions around sunspots. Their frequency varies from several a day, when the sun is particularly active, to less than one a week during quiet periods.
    Large flares are less frequent than smaller ones. Solar activity varies within an 11-year cycle at the peak of which there are typically more sunspots and therefore more solar flares.
    What affect can they have on earth?

    X-rays and UV radiation emitted by solar flares can cause long-lasting radiation storms the Earth’s ionosphere – the uppermost part of the planet’s atmosphere – and trigger radio black-outs around the world.

    Each flare produces streams of highly energetic particles in the solar wind and the Earth's magnetosphere that can present radiation hazards to spacecraft and astronauts. A solar flare on January 20, 2005 released the highest concentration of protons ever directly measured and took just 15 minutes to reach Earth, indicating a velocity of approximately one-third light speed.
    Scientists have warned that a really big solar eruption could destroy satellites and wreck power and communications grids around the globe.

    Nasa recently said that Britain could face widespread power blackouts and be left without critical communication signals for long periods of time if the earth is hit by a once-in-a-generation “space storm”.

    How do we know they are coming?
    The methods currently used to predict flares are problematic and it is not presently possible to tell when an active region of the Sun will produce a flare.
    But certain properties of sunspots and active regions of the Sun correlate with flaring. Magnetically complex regions called delta spots produce most of the largest flares, so a simple scheme of sunspot classification is commonly used as a starting point for predicting flares. Predictions are usually stated in terms of the probability of a flare within 24 or 48 hours. The US National Oceanic and Atmospheric Administration issues forecasts of this kind.

    A number of space missions have been deployed to observe flares, including Hinode - a new spacecraft launched by the Japan Aerospace Exploration Agency in 2006 to observe the phenomena in closer detail.

    When were they discovered?
    The first flare ever to be observed was also the most powerful on record. It occurred in 1859 and was reportd independently by the British astronomers Richard Carrington and Roger Hodgeson. The scientists observed the flare as the localised brightening of small areas within a group of sunspots. The event left a trace in Greenland ice in the form of nitrates and beryllium-10, which allow its strength to be measured today.
