There is really no point of putting up a story about every time we have a big flare, because this could go on for awhile and is really quite normal behavior.

    From the article:
    Space weather forecasters say this spate of strong solar flares is not consistent with normal solar behavior. The sun, which follows an 11-year activity cycle, has been quieting down since the last peak in 2000.

    Although we humans have been looking at the sun since before we climbed out of the trees (and our moms have been telling us not to even longer), it's almost silly to say that any observation of our local star is "not consistent with normal solar behavior." Just how many of those 11-year cycles have been recorded?

    If the ancient Chinese were using pinhole solar viewers [stanford.edu] to count sunspots for the past 5000 years, that would be one thing. But as has been posted in every Slashdot story on the subject, we have maybe 200 years of scientific data (of varying quality) out of the sun's five billion year history. Even W's pollsters would tell you that sample size is too small.
  • There is a perceptible slowing of the Internet as the flare hits our magnetosphere -- at first I thought this might be satellite-related, however the slowdown appears to occur within the country as well as to overseas links. Perhaps this is related to the effect on the power grid?

    When I read this line, "I have not seen anything like it in my entire career as a solar physicist. The probability of this happening is so low that it is a statistical anomaly.", I cringed. Either a) This guy thinks his model is great & really believes that this is a 1/1,000,000,000 event, or b) he knows that this indicates a whole in his model, but the reporter ripped the quote out of context to make the story more sensational.

    A little statistics primer is in order. In order to quote odds on anything, a statistician needs a model, generally based on existing data. When there is an event that's off the charts, it will usually indicate to the scientist (or engineer) that there is a deficiency in their model (or their process is out of control, for manufacturing types). If I were a solas scientist, this event would indicate to me that the model is not adequate for predicting this sort of thing. Which makes sense, since we probably only have 40 years worth of data; you expect to be thrown a curve-ball every now and then.

    So I doubt it really is a statistical anomanly; maybe these solar-flare pairs occur every 50 years or so & that's why we haven't seen it before. But either the reporter needs to better explain the meaning of the quote, or the quotee needs to take a basic course on the limits of statistical probability.
    • The sun has been around a long time; so any models we do have are based upon a very small set of information that is a subset of a huge amount of information we do not have.

      For that reason alone, I doubt that this is as rare an event as some may make it out to be.
  • Sure am glad CNN alerted us at 12:35 PM Eastern that the flare could impact us as early as this afternoon.

    Luckily our terrestrial weather forcasting (which has a far greater impact on our lives) is a little better. I've had more warning before tornados!

    Excerpt:
    "If (when) this flow of charged particles and embedded magnetic field collides with the Earth, it dramatically disrupts Earth's geomagnetic field and ionosphere, changing the terrestrial magnetic fields ... This magnetic field change, which occurs fairly rapidly, then induces currents in nearby conductors. ... In those areas that do not have high conductivity, such as those areas that contain igneous rock, the induced current flows through any available current path-typically, the long utility system lines for power, gas, oil, water, and telecommunications."
