#filament
On March 11th, a huge #filament of #magnetism filled with dark #plasma erupted from the southwestern limb of the #sun. NASA's Solar Dynamics Observatory recorded the structure hurling itself into space:
"Dark plasma" is not a special kind of plasma; it's just cooler and less luminous than the background sun. It is also denser than surrounding gas. These characteristics give the material extra "punch" as it flies out of the sun's atmosphere.
This eruption formed a #CME, which was seen flying away from the sun shortly after the blast. NOAA analysts have modeled the CME and determined that it could graze Earth's magnetic field on March 15th, producing a G1-class geomagnetic storm.
