Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2025-03-16T12:00Z ( SOHO: LASCO/C2 )
All Detecting Spacecrafts:
SOHO: LASCO/C2
SOHO: LASCO/C3
Activity ID: 2025-03-16T12:00:00-CME-001 (version 5)
Source Location: N10W10
Note Keyword:
Faint: Faint event; may affect type assignment
HAL: Halo CME
Source Signature Keyword:
PEA: Post eruption arcade
BR: Brightening
DIM: Dimming
Morphology Keyword:
O: Other
Note: An extremely faint fuzzy CME/outflow/possible partial halo to the north-northwest, seen in SOHO LASCO C2 and even more faintly for a few early timestamps in C3, but not seen in STEREO A COR2, likely because of faintness. Better seen in running difference imagery. Its source is most likely the medium-size but pretty faint dimming seen starting ~2025-03-16T10:09Z, signifying eruption to the northwest of Active Region 4023 and centered (~N20W10), seen in SDO AIA 193 and GOES SUVI 284.

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.
