Note: Wide, relatively slow CME seen to the northeast in SOHO C2, C3, and GOES CCOR1 and to the north in STEREO Ahead COR2 clearly associated with a strong far-sided eruption as evidenced by a large-scale prominence eruption occurring off the northeast limb seen best in GOES SUVI 284 seen starting around 2025-05-13T14:05Z but clearly visible more broadly by 15:00Z.

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
