Broader View of Solar Outbursts

With the STEREO (Behind) Heliospheric Imager (HI), we can track the solar burst known as coronal mass ejections (CMEs) across a broad expanse of space stretching millions of miles (a 20 degree field of view). It is a wide-angle visible-light imaging system designed to detect CME events. This video clip shows several solar bursts of CMEs as they expand into space over one week period (Aug. 28 – Sept. 3, 2013). In these images, the Sun is just to the left of the frame and Earth is the bright object to the right (the downward line is a visual artifact). Credit: STEREO/NASA.
