Activity ID: 2025-10-17T17:00:00-CME-001 (version 1)
Source Location: N24W79
Active Region Number: 14246
Note Keyword:
GAP: Data gap

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 79.0 42.0 428.0 S 41.0 2025-10-18T01:53Z Parameters based on the potential source location as well as the best fit using SOHO LASCO C3 and GOES CCOR-1 imagery. STEREO A COR2 was not used in this measurement due to limited frames and reliability on size and directionality of CME based on SOHO and GOES imagery. 1: Result 1 (2.0 AU)
