Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2023-08-18T06:12Z ( SOHO: LASCO/C2 )
All Detecting Spacecrafts:
SOHO: LASCO/C2
SOHO: LASCO/C3
STEREO A: SECCHI/COR2
Activity ID: 2023-08-18T06:12:00-CME-001 (version 1)
Note Keyword:
Faint: Faint event; may affect type assignment
Source Signature Keyword:
OFL: Moving/Opening field lines
Morphology Keyword:
L: Loop
Note: This faint CME is visible to the N in SOHO LASCO C2/C3 and STEREO A COR2 Difference coronagraph imagery. The source is beyond the limb and likely at a high latitude. Moving/opening field lines can be seen over the north limb in SDO AIA 171 at about 2023-08-18T05:30Z. This CME is measured with an approximated longitude due to a lack of stereoscopic viewpoints.

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.
