Observing CMEs

Observe CME on far side of the sun

A filament erupted on the sun on August 31, 2012, and NASA’s Solar Dynamics Observatory (SDO) caught the action from noon EDT to 1:45 a.m. the next morning.

As you watch the video image, the eruption took place in the lower left corner of the sun.

The images were taken of light at 304 Angstroms and 171 Angstroms, which makes it possible for scientists to observe the sun’s atmosphere or corona in more detail.

This particular coronal mass ejection (CME) event was also observed by STEREO and SOHO, and their images are added as well.
