    Well not quite, but one as bad as the 1859 flare could cause
    widespread loss of power, system failures, ATM failures, etc etc.

  2. But they make great northern lights !

    No it's Bill Gates, almost as big, certainly as damaging to society but
    nowhere near as pretty.

    My jeans are no good - is it the flares?

    Unlikely - a big enough radiation surge to crash Windows would make
    mincemeat of DNA .

    What are you saying?!?!?!?

    The radiation of a single anti-Gates thought at 50 paces can crash
    Windows, fergawdsake! :)

    A single neutrino passing through the memory or CPU can crash Windows,
    even though neutrinos do not interact (much) with matter .

    Anyone out there have any info of this flare creating any problems like
    power failures, etc? Apparently Canada would have been hit the worst? Any
    info or feedback?

    Regards.
     
  9. If you live in a northern location where they're visible. I don't
    think they'll get as far south as So. Calif. Especially with the poor
    visibility caused by the wildfires. During the early morning and late
    afternoon, the sun looks orange like it does at sunset.

    ATM failures? Like automatic teller machines? Well, use your credit
    card. If you meant ATM as in Asynch Transfer Mode, AKA datacomm
    links, well many if not most of those are over fiber, so
    those shouldn't be affected.

  10. Andre, get a close grip on yourself, then explain how such system
    failures could occur. Obviously solar flares disrupt radio
    communications, but after many years of experiencing these things,
    don't you think that by now major system operations have a handle on
    this periodic problem?

    Harry C.
     
  11. Given that there have been at least 43 recorded cases of satellite
    damage due to solar flares including the total loss of a broadcast
    satellite several years ago, it would appear not. Not to mention the
    incredible currents that can be induced in the power grid due to
    compression of the Earth's magnetic field. How would you propose that
    they shield the system from such effects? BTW, last time I looked, most
    semiconductors in use were not radiation hardened. FYI, HF
    communications for the airlines was all but eliminated yesterday and the
    solution was to tell the pilots not to deviate from their scheduled
    course (like to avoid a storm or turbulence). So perhaps you're right
    after all, they've got it completely under control. ;-)
     
  12. I would suggest the obvious...if it's not broken, don't try to fix it.
    Yes, and the the semoconductor damage resulting from solar flares is?

    Actually the airlines have not used HF communications since around the
    1940s. It's a moot point, and no airline schedules were affect by the
    solar flares, nor much of anything else as any educated person would
    expect.
    Of course they have. This is why there were no headlines today about
    the terrible disruptions resulting from the solar flares.

    Anthony (or whatever your real name is) you have no clue.

    What's next, you're going to unleash stil another of your nitwit
    hacker attacks against me? Try harder, you third shift, computer
    operator looser!

    Harry C.
     
  13. They still do use it for transoceanic flights. As they are still not
    using satcom there is no other way.

    Michael
     
  14. Actually, power companies from Sweden to New Jersey temporarily cut
    production to prepare for the possible surges.
    It's not so much the actual flares themselves, it's the heavier
    particles that do the damage when they hit the Earth 1-5 days after the
    flare.
    You are completely out of your gourd on this one, but of course you will
    never admit it.
    There were no headlines because they lucked out again.
    Yet another typical Harry C ad-hominem attack. What are you talking
    about hackers, are you suggesting that I have committed some kind of
    computer crime against you?

    Speaking of losers, at least I'm not a full fledged member of the
    "Crackpot" list on sci.physics. I can also proudly say that I haven't
    been proven to be a liar many dozens of times on usenet, though the
    Google archives show you to not be quite so fortunate.
     
  15. Anyone with a basic knowledge of electicity can see that huge induced
    currents caused by natural phenomena such as lightning and geomagnetic
    storms can disrupt any electric system. The operators can take some
    precautions, but using lightning as an example, they're not going to
    go to the extreme precaution of putting everything in a faraday
    shielded cage. So the operators are going to run systems as
    conservatively as they can within reasonable limits, and hope that the
    effects are minimal. But that doesn't mean that nothing will happen.
    After all, it has in the past. So "get a grip on yourself" and be
    prepared to eat crow if a major electrical system does go down.

  16. BZZZT! You don't know what you're talking about, Harry Cockeyed.
    Just another one of your ad hominem attacks. Go fly a kite. In a
    thunderstorm. **PLONK**

  17. He is also the buffoon who claimed he's holier than thou because he
    has a degree in engineering. He must have got it from the U. of
    Afghanistan, and his teacher was Osama Bin Lyin'.

  18. I wouldn't be this way towards him if he could simply apologize for a
    previous unprovoked ad-hominem attack and admit that he was wrong in his
    claims. But since he can't seem to muster up enough integrity to be a
    stand up guy and simply admit that he doesn't know everything......
     
  19. Sorry "Anthony" but good technology is a matter of defensive design,
    not a matter of luck. There were no news reports describing dramatic
    effects of the solar flare simply because there were no dramatic
    effects to our infrastructure resulting from the solar flare, nor were
    any anticipated.

    The biggest news in this connection is that many ham operators were
    able to exploit the resulting ionization in the upper atmosphere, and
    I'm told that the aurora was quite spectacular in regions where it
    could be seen.

  20. I stand corrected then. I may have been misled by the fact that most
    major communication equipment firms no longer seem to be producing HF
    communication suites for aviation applications. Do FAA sites still
    support HF communications?

    Marine electronics is, of course, quite a different situation, and
    there HF SSB remains in widespread use.
