NASA Puts Us On Guard For 2012

Experts predict that Northern Lights, also known as the Aurora Borealis, will shine and will be observed in 2012 at the highest level in the last 50 years. Since 2007, the phenomenon of lights grew in intensity and according to NASA scientists, will reach its climax in less than two years. The Aurora Borealis could be more than a delightful spectacle for the eyes if in 2012 the Northern Lights will be at the expected magnitude, they could cause disruptions of GPS and mobile phone networks and electrical networks could affect several countries.

The event will be challenged by what is known as Solar Maximum - a process whereby the magnetic field in the equatorial zone of the Sun rotates faster than a polar region of the planet. The solar cycle requires, on average,about 11 years to go from a maximum to the next one, this time varying between less than 9 and not more than 14 years. The most recent Solar Maximum occurred in 2000 and NASA scientists believe that the next will be the most "prolific" from 1958 until today. Then, over half a century ago, The Aurora Borealis stunned the people of Mexico when it appeared across the sky. NASA experts believe that the Northern Lights that could occur in less than two years may become visible to the South all the way, to the City of Rome. Additional evidence in support of the theory of solar wind intensifying is by Icelandic photographer, Orvar Thorgiersson from Reykjavik. He been shooting Northern Lights from 2007, and from year to year, the snapshots obtained illustrates a coloring and a propagation more and more accentuated. Orvar believes that in 2012 scenes in the sky would not be able to be described in words.
