The first strong solar flare in four years occurred on Feb. 14, 2011, as captured here by NASA's Solar Dynamics Observatory spacecraft. This solar flare led to warnings that a geo-magnetic storm could disrupt communications and electrical supplies once it reaches the earth's magnetic field. Another solar storm is hitting the Earth on Jan. 24, 2011.
