NASA's SOHO Captures Halo CME August 7th [HD Video]
NASA image acquired August 7, 2010
SOHO captured this video clip of a full halo coronal mass ejection (CME) that blasted a substantial cloud of particles away from the Sun (Aug, 7, 2010). The majority of the cloud went to the left with only a smaller portion heading to the right, suggesting that it would not likely have any strong impact on Earth. A “halo” cloud is one that appears to surround the Sun on all sides as it expands, meaning it is heading somewhat towards Earth or away from it. The still and movie are generated by processing the changes from one frame to the next to highlight those changes, thus, we call this a “difference movie.”
NASA Goddard Space Flight Center is home to the nation's largest organization of combined scientists, engineers and technologists that build spacecraft, instruments and new technology to study the Earth, the sun, our solar system, and the universe.
