The X8.2 Flare of September 2017, as Seen by SDO

Between September 9-10 of 2017, the Sun launched a series of three coronal mass ejections (CMEs), culminating with an X8.2 flare from the eastern limb, as the active region was rotating away from the Earth. These events rippled across the solar system, and were detected by multiple NASA missions.

A slow (500 km/s) CME was launched at 23:46UT on September 9. A second faster CME (1000km/s) was launched on September 10 at 02:16UT and the fastest CME (2600 km/s) was launched at 16:54 UT. The faster CMEs would eventually catch up with the slower CME and merge into a single CME moving through the solar system.

These image sequences from SDO are selected at a higher time resolution (12 seconds between frames) compared to some of the older content related to these events.
