Warning: Sunspot cycle beginning to rise

It's time for the sun to move into a busier period for sunspots, and while forecasters expect a relatively mild outbreak by historical standards, one major solar storm can cause havoc with satellites and electrical systems here.

    Time to start installing solar panels.

    I thought we were entering a protracted Mini-Ice Age?

    New Denial Angle should be revealed next week. Don't despair, they're spinning something up as we speak.

    The 1859 storm shorted out telegraph wires, causing fires in North America and Europe, sent readings of Earth's magnetic field soaring, and produced northern lights so bright that people read newspapers by their light.

    I think this was one of the theories for the end of the world in 2012.

    From what I've read eventually it will be, your time line is off by a couple of thousand years though.

    Who knows.

    This is due to come pretty close in 2029.

    This might be a big deal id it didnt happen in cycles for the last few eons.
    I have no idea why this is considered big news as its been going on forever,radio ham operators look forward to the high end of the cycle as they can then work the skip and transmit and recieve all over the world.

    For some it means high winds and nice auroras for a year or two.
    It's a perfectly explainable phenomena.
    No need to panic or be afraid.

    If they cause solar storms that are intense enough, they can wreak havoc with communications and power grids. Remember what happened in Quebec in 1989?

    Like hurricanes, a weak cycle refers to the number of storms, but it only takes one powerful storm to create chaos, said scientist Doug Biesecker of the National Oceanic and Atmospheric Administration's space weather prediction center.

    A report by the National Academy of Sciences found that if a storm as severe as one in 1859 occurred today, it could cause $1 trillion to $2 trillion in damage the first year and take four to 10 years to recover.
    The 1859 storm shorted out telegraph wires, causing fires in North America and Europe, sent readings of Earth's magnetic field soaring, and produced northern lights so bright that people read newspapers by their light.

    Today there's a lot more than telegraph lines at stake. Vulnerable electrical grids circle the globe, satellites now vital for all forms of communications can be severely disrupted along with the global positioning system. Indeed, the panel warned that a strong blast of solar wind can threaten national security, transportation, financial services and other essential functions.

    The solar prediction center works closely with industry and government agencies to make sure they are prepared with changes in activity and prepared to respond when damage occurs, Biesecker said in a briefing.

    While the most extreme events seem unlikely this time, there will probably be smaller scale disruptions to electrical service, airline flights, GPS signals and television, radio and cell phones.

    On the plus side, the solar storms promote the colorful auroras, known as the northern and southern lights, high in the sky over polar areas.

    That was a good one for sure but its not abnormal,I think it goes in cycles of 7 or 8 years before it hits its peak.There was a big scare campaign years ago about all the impending doom that was going to occur at the last high cycle but it never did.
