NASA released video of a large solar flare that erupted February 24. Scientists say the flare was directed away from earth and should not disrupt satellites or communications.

    • “In modern times, the largest solar flare measured with instruments occurred on November 4, 2003 (initially measured at X28 and later upgraded to X45).” http://en.wikipedia.org/wiki/Solar_flare
      The 2003 solar flare happened during solar minimum. It was extremely unusual!

      We are two years away from solar maximum. This latest activity is likewise highly unusual.

      Electrical grids & anticipated solar flares of 2012

      Mainstream scientific concern about 2012 has grown since a recent National Research Council report funded by NASA and issued by the National Academy of Sciences, entitled “Severe Space Weather Events: Understanding Economic and Societal Impact” which details the potential devastation of 2012 solar storms on the current planetary energy grid and because of the inter-linkages of a cybernetic society, on our entire human civilization.
      According to New Scientist, science’s concern is a repetition of the 8-day 1859 “Carrington event,” a large solar flare accompanied by a coronal mass ejection (CME) that flung billions of tons of solar plasma onto the earth’s magnetosphere and disrupted Victorian-era magnetometers and the world telegraph system.
      The New Scientist states, “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.”
      The next solar maximum is expected to occur in 2012. New Scientist reports that Mike Hapgood, head of the European Space Agency's space weather team states, "We're in the equivalent of an idyllic summer's day. The sun is quiet and benign, the quietest it has been for 100 years," "but it could turn the other way."
      The modern electrical high-power grid magnifies the impact of solar flares. Since the grid is linked into major aspects of modern society, the effects of another Carrington event would be devastating. The National Academy of Sciences report states: “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.” The New Scientist states: “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.”
      China, which is installing a high-power electrical grid more vulnerable than that of the U.S., Europe and other developed nations will be similarly impacted.
      The solar coronal mass ejection from the 1859 Carrington event arrived on earth in less than 15 minutes, which is faster that our early warning system NASA's Advanced Composition Explorer (ACE) can detect.
      European Space Agency space weather head Mike Hapgood states, "I don't think the NAS report is scaremongering. “Scientists are conservative by nature and this group is really thoughtful," he says. "This is a fair and balanced report."

      The internet has existed since 1988, I began using it in 1989, and the World Wide Web was introduced two years later, so there has already been 2 solar activity periods, this is the third. In the past, 22 years of my use of the internet, neither of the 2 previous periods of solar activity interfered in any way in my internet experience.

      Jeez, doesn't time fly when you're having fun. You are right, of course. But do you not agree there's a huge increase in the sheer number of possible interferences, even since 2000? I mean, we were all freaking out about Y2K, but we were doing it slowly on dial up, not satellite. Or were the phone companies all relaying by satellite then?

      The reason why Y2K didn't have the catastrophic impact feared is due to a veritable army of "old timer" programmers (my older brother among them) who worked relentlessly 7 days a week for many months fixing the old programming in the old systems that were still in place in airports, hospitals, rail services, electric plants, nuclear plants, etc., world-wide. As for phone companies and satellites, I do know that inter-continental telephone communications via satellite have been around since the mid-sixties.

      Y2K was also hyped up doomsday by the press.
      The solar storms however can be devastating to the power grid. The aurora borealis can and does induce large voltage spikes in transmission lines and can blow out step up and step down transformers at the substations. It happens in Canada often during peak solar cycles and if it exceptionally strong it will reach into the USA system. Satellites can usually be turned to avoid the worst of the damaging energy however damage to them is common and can destroy them.
