Is Dec 12 2012 going to be doomsday? Not sure, but at least there won’t be “Killer Solar Flares” burning the planet down. The fact that fact that solar activity is currently ramping up in its standard 11-year cycle is true, but won’t be the worst in 2012, but late 2013 or 2014. Since, it is an eleven-year cycle, a lot of us have lived through multiple of those solar flares.
This is not to say that space weather can’t affect our planet. The explosive heat of a solar flare can’t make it all the way to our globe, but electromagnetic radiation and energetic particles certainly can. Solar flares can temporarily alter the upper atmosphere creating disruptions with signal transmission from, say, a GPS satellite to Earth causing it to be off by many yards. Another phenomenon produced by the sun could be even more disruptive. Known as a coronal mass ejection (CME), these solar explosions propel bursts of particles and electromagnetic fluctuations into Earth’s atmosphere. Those fluctuations could induce electric fluctuations at ground level that could blow out transformers in power grids. The CME’s particles can also collide with crucial electronics onboard a satellite and disrupt its systems.
In an increasingly technological world, where almost everyone relies on cell phones and GPS controls not just your in-car map system, but also airplane navigation and the extremely accurate clocks that govern financial transactions, space weather is a serious matter.
But it is a problem the same way hurricanes are a problem. One can protect oneself with advance information and proper precautions. During a hurricane watch, a homeowner can stay put . . . or he can seal up the house, turn off the electronics and get out of the way. Similarly, scientists at NASA and NOAA give warnings to electric companies, spacecraft operators, and airline pilots before a CME comes to Earth so that these groups can take proper precautions. Improving these predictive abilities the same way weather prediction has improved over the last few decades is one of the reasons NASA studies the sun and space weather. We can’t ignore space weather, but we can take appropriate measures to protect ourselves.Source: www.nasa.gov
