Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2026-07-11T18:53Z ( SOHO: LASCO/C2 )
All Detecting Spacecrafts:
SOHO: LASCO/C2
STEREO A: SECCHI/COR2
GOES: CCOR-1
Activity ID: 2026-07-11T18:53:00-CME-001 (version 1)

Note: CME observed to the W in STEREO A COR2 and W/SW GOES CCOR-1 following behind the 2026-07-11T16:09Z CME, not in SOHO LASCO C2/C3 in real-time due to an ongoing outage. The source of the CME may likely involve former Active Region 14479 or AR 14478, estimated to be located ~N17W165 and ~S05W155 at this time.

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.
