2012?

One of the sites I love to visit is Spaceweather.com, a conglomeration of NASA and earth observations on the sky. It has wonderful photos of various events, Auroras, comets, meteor showers, atmospheric optics and the like. t also keeps a close watch of geomagnetic storms and provides alerts and info. Today's post was concerning an event in 1859, which may affect all of us electronic people. The post:
"SEVERE SPACE WEATHER: The National Academy of Sciences has just released the results of a study entitled Severe Space Weather Events--Understanding Societal and Economic Impacts. The 132-page document examines what might happen to our high-tech modern society in the event of a super solar flare followed by an extreme geomagnetic storm. Such a storm did occur in the year 1859. It electrified telegraph lines, shocking technicians and setting telegraph papers on fire; Northern Lights as far south as Cuba were so bright, you could read a newspaper by their eerie glow.

According to the report, "a contemporary repetition of that event would cause significantly more extensive (and possibly catastrophic) social and economic disruptions." The report warns of widespread failures in telecommunications, electric power, banking and finance, and transportation; even water supplies could be disrupted. The total economic impact in the first year alone could reach $2 trillion--about 15 times greater than the costs of Hurricane Katrina. Depending on damage, full recovery from the solar storm could take 4 to 6 years.

No one knows how often super solar storms occur. We've only seen one like it in the past 200 years. The next one could be another 200 years away--or just 200 days. All the more reason to study space weather!

Now. why 2012? Well that is the predicted next solar maximum!
