Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2025-01-16T21:36Z ( SOHO: LASCO/C2 )
All Detecting Spacecrafts:
SOHO: LASCO/C2
SOHO: LASCO/C3
Activity ID: 2025-01-16T21:36:00-CME-001 (version 1)
Note Keyword:
Faint: Faint event; may affect type assignment
FF: Event fails/disappears before exiting COR2
GAP: Data gap
OVR: Event partially overlaps with another CME
Source Signature Keyword:
Morphology Keyword:
L: Loop
Note: Very faint SW CME with a clear front. No clear source has been found, but there is possibly some movement of field lines on/behind the SW limb seen in AIA/SUVI 171 and 193/195, although this is rather speculative.

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. This is a helpful flag if you would like to download only one most accurate CME analysis per CME per Measurement Type
