CME initiation (click on image to see movie)
|
This full Sun movie shows an XRT observation of the starting phase of
a coronal mass ejection, which shows up in STEREO data about one hour
later (the event starts around 23 UT on 2009/02/10). The core of the
active region is saturated, but the weak emission from the fast moving
ejecta can clearly be seen on the East limb (left) of the Sun. Note
that the diffuse, wedge shaped emission that is seen at the end of the
movie is due to stray light from the X-ray mirror and the bright core
of the active region is due to CCD saturation. Therefore both
artifacts in the movie are not of solar origin.
