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.

CME Analysis M2M_CATALOG LE true SWPC_CAT -20.0 46.0 437.0 S 10.0 2025-06-04T09:14Z Approximate analysis based on the fit of this narrow CME in two coronagraphs (SOHO LASCO C3 and STEREO A COR2). No source was found for this event, however it is worth noting that the CME latitude and longitude are just north of the recently opened coronal hole which was gradually 'opened' by a very slow motion eruption associated with the 2025-06-03T07:48Z CME.
