Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2025-04-04T10:12Z ( SOHO: LASCO/C2 )
All Detecting Spacecrafts:
SOHO: LASCO/C2
SOHO: LASCO/C3
Activity ID: 2025-04-04T10:12:00-CME-001 (version 1)
Note Keyword:
Faint: Faint event; may affect type assignment
GAP: Data gap
OFL: Outflowing material at the back of the CME
Source Signature Keyword:
Morphology Keyword:
L: Loop
Note: Faint front seen to the NE in SOHO LASCO C2/C3 only due to a STEREO COR2A data gap beginning at 2025-04-04T10:38Z, better seen in SOHO LASCO running difference imagery than white light. No source for this CME is observed in SDO AIA and GOES SUVI imagery.

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.
