    Solar Flares Put Power Grid at Risk

    While a video of the eruption captured by NASA’s Solar Dynamics Observatory showed an enormous plume spraying from the sun, this solar tantrum would not be the big one — it would not be the 1859 event all over again.
    Sept. 1 of that year saw the largest solar flare on record, witnessed by British astronomer Richard Carrington. While tracing features of the sun’s surface, which Carrington had projected via telescope onto paper, he saw a sudden flash emerge from a dark spot. Although such sunspots had sparked curiosity for centuries — Galileo famously drew them, too, in the early 1600s — Carrington had no idea what the flash could mean.
    Within hours, telegraph operators found out. Their long strands of wire acted as antennas for this huge wave of solar energy. As this tsunami sped by, transmitters heated up, and several burst into flames. Observers in Miami and Havana gaped skyward at eerie green and yellow displays, the northern lights pushed far south.
    A knockout punch
    Such a “Carrington event” will happen again someday, but our wired civilization will suffer losses far greater than a few telegraph shacks.
    Communications satellites will be knocked offline. Financial transactions, timed and transmitted via those satellite, will fail, causing millions or billions in losses. The GPS system will go wonky. Astronauts on the space station will huddle in a shielded module, as they have done three times in the past decade due to “space weather,” the scientific term for all of the sun’s freaky activity. Flights between North America and Asia, over the North Pole, will have to be rerouted, as they were in April during a weak solar storm at a cost to the airlines of $100,000 a flight. And oil pipelines, particularly in Alaska and Canada, will suffer corrosion as they, like power lines, conduct electricity from the solar storm.

    It's all good. My tin foil will keep the solar flares out.
