Astronomie - SDO sieht starken CME-Ausbruch

.

There is an active sunspot on the farside of the sun. Yesterday, Feb. 25th, it blasted a coronal mass ejection (CME) over the sun's northwestern limb, shown here in a movie from the Solar and Heliospheric Observatory:
NASA's STEREO-Ahead spacecraft is stationed over the farside of the sun, almost directly above the CME. Images from the spacecraft pinpointed the source of the blast: It is active sunspot AR1678, which rotated off the Earthside of the sun just a few days ago.
