The sun is predicted to enter a period of high electromagnetic activity that may interfere with electricity transmission and communications on earth.
On Feb. 6th, NASA’s twin STEREO probes moved into position on opposite sides of the sun, and they are now beaming back uninterrupted images of the entire star—front and back.
“For the first time ever, we can watch solar activity in its full 3-dimensional glory,” says Angelos Vourlidas, a member of the STEREO science team at the Naval Research Lab in Washington, DC.
NASA released a ‘first light’ 3D movie on, naturally, Super Bowl Sunday:
“This is a big moment in solar physics,” says Vourlidas. “STEREO has revealed the sun as it really is–a sphere of hot plasma and intricately woven magnetic fields.”
Each STEREO probe photographs half of the star and beams the images to Earth. Researchers combine the two views to create a sphere. These aren’t just regular pictures, however. STEREO’s telescopes are tuned to four wavelengths of extreme ultraviolet radiation selected to trace key aspects of solar activity such as flares, tsunamis and magnetic filaments. Nothing escapes their attention.
As we have reported previously aging transformers and towering transmission towers are especially susceptible to the effects of solar flares. As many as 130 million people may find themselves without power in the US.
Over the past thirty years, Kappenman has accumulated a vast and compelling body of evidence indicating that sooner or later a major blast of EMP (electromagnetic pulse) from the Sun, a space weather Katrina, will knock out the electrical power grid and bring society to its knees.
