Here is the flare and ejection from the sun captured by the NASA/SDO spacecraft. The video was created by LMSAL showing us emission in 3 wavelengths of light, 171, 193, and 131. This gives us a picture of solar coronal plasma heated from 1-20+ million degrees. | The Sun Today: Solar Facts and Space Weather | Facebook
