Note: Fast CME seen to the west in SOHO C2, SOHO C3, STEREO A COR2A, and GOES CCOR-1 which has no clear source on the Earth facing disk in any EUV imagers, indicating that the source is likely associated with far-sided eruptive activity relative to the Earth-facing solar disk.

Prime?"primary flag" which is either True or False. If there are multiple CME analysis entries for a single CME, this flag would indicate which analysis is considered most accurate per measurement type. This is a helpful flag if you would like to download only one most accurate CME analysis per CME per Measurement Type
