Note:

Triangulation between SOHO LASCO C2/C3, GOES CCOR-1, and STEREO A COR2. The CME appears as two distinct pieces to the N and NE with an appreciable gap between, yet likely launch and travel together as one signature from the source prominence, so this anaylsis encompasses the entire eruption as one leading edge feature.
