Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2025-04-19T19:36Z ( SOHO: LASCO/C2 )
All Detecting Spacecrafts:
SOHO: LASCO/C2
SOHO: LASCO/C3
Activity ID: 2025-04-19T19:36:00-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:
OFL: Moving/Opening field lines
Morphology Keyword:
Note: CME first visible in running difference imagery to the S about half way into the FOV of SOHO LASCO C2 starting at 2025-04-19T19:36Z. Also seen to the S in SOHO LASCO C3. CME is covered by a data gap in STEREO A COR2. The CME could be continued outflow following CME: 2025-04-19T17:00Z. A possible source is some faint field line movement to the S starting around 2025-04-19T18:30Z best seen in SDO AIA 171 and SDO AIA 193.

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.
