Solar Storm

  1. Jun 26, 2009 #1
    I am pretty sure ya'll heard about the Solar storm that is going to happen around the year 2012 and scientist predicts that its gonna wipe out all communication sources like the satellites, gps etc....So if the prediction turns out to be true i wonder how we are gonna rebuild all the destruction.

    We have already had several of these sunspot maxima ("solar storms") since the advent of communications satellites. We are all still here. The internet still works.

    What scientific journal article told you that the proverbial skies were going to fall during the next solar maximum?

    Um some people just want to connect 2012 with something significant. Don't hold one's breath.

    As for the solar cycle.

    The solar activity peaked in 2000, and there was a second lower peak in 2002.

    Predictions in 2007 (First Solar Cycle 24 Prediction April 2007) put the maximum as early as late 2011 (most intense) to as late as mid-2012 (least intense).

    Predictions in 2009 (May 2009 Solar Cycle 24 Prediction Update) put the peak around late 2003 to early 2004, and the intensity being somewhat less than the previous cycle (Cycle 23), which peaked in 2000 (two peaks with a lesser peak in 2002).

    In addition to Jim's and Astro's comments, the increased solar activity may temporarily impair communications, but most likely will not cause physical damage to the satellite infrastructure.

    I too would like to read the mainstream, scientific article that you got your information from. Please post a link.

    Things have slid a bit and the next solar cycle is now predicted to peak in 2013
    and to be below average:

    For some reason, very large solar storms do occur during low solar periods. There is evidence the sun is moving towards a Maunder minimum. The sun has for some reason had very large x-ray type flares late in the solar cycle which does not match other cycles. There has also been x-rays generated from small sunspots.

    A super solar storm does pose a significant risk to global electrical infrastructure and communications satellites.

    The problem is the coronal mass ejection (CME) creates massive electrical fields in the earth’s ionosphere which induces currents in the power grid which will overload and damage power equipment, such power transformers. Large power transformers have a delivery time of roughly a year and as they have a normal life expectancy of 30 years there is limited manufacturing capability. There have been estimates of power outages and widespread brownouts of a year or more, if a Carrington like solar storm were to occur today.

    A Carrington event would also have a significant effect on power generation, such nuclear reactors which require a stable load, to dissipated the energy created. I believe many reactors would need to be shutdown.
