Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2025-10-31T06:23Z ( STEREO A: SECCHI/COR2 )
All Detecting Spacecrafts:
STEREO A: SECCHI/COR2
SOHO: LASCO/C2
SOHO: LASCO/C3
GOES: CCOR-1
Activity ID: 2025-10-31T06:23:00-CME-001 (version 2)
Note Keyword:
Faint: Faint event; may affect type assignment
OFL: Outflowing material at the back of the CME
OVR: Event partially overlaps with another CME
Source Signature Keyword:
Morphology Keyword:
O: Other
Note: CME observed to the E in SOHO LASCO C2/C3, GOES CCOR-1, and faintly in STEREO A COR2, overlapping with outflow from larger CME 2025-10-31T00:24Z. No distinct source for this front is observed, it may be far-sided and/or outflow following the larger CME 2025-10-31T00:24Z which was far-sided as well (swpc_cat triangulation to S04E97).

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.
