Q: Is there a danger from giant solar storms predicted for 2012?
A: Solar activity has a regular cycle, with peaks approximately every 11 years. Near these activity peaks, solar flares can cause some interruption of satellite communications, although engineers are learning how to build electronics that are protected against most solar storms. But there is no special risk associated with 2012. The next solar maximum will occur in the 2012-2014 time frame and is predicted to be an average solar cycle, no different than previous cycles throughout history.
Traduciendo, y en resumen.
"...no hay un riesgo especial para el año 2012. El próximo máximo del ciclo solar se prevé para 2012-2014, y se estima que sea un ciclo medio, no diferente de los ciclos anteriormente registrados"
Saludos y unas
