Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2024-01-12T12:12Z ( SOHO: LASCO/C2 )
All Detecting Spacecrafts:
SOHO: LASCO/C2
Activity ID: 2024-01-12T12:12:00-CME-001 (version 3)
Note Keyword:
DPL: CME exhibits dimpled front
Faint: Faint event; may affect type assignment
FF: Event fails/disappears before exiting COR2
Source Signature Keyword:
PEA: Post eruption arcade
OFL: Moving/Opening field lines
Morphology Keyword:
O: Other
Note: Very faint narrow CME in the West best seen in SOHO LASCO C2. Its front is super diffuse in C3. Its source is likely backsided, as indicated by some faint movement of field lines behind the limb in AIA 171 and by very minor/non-impressive post eruptive arcades seen in AIA 193 on/behind the NW limb after 12:30Z. Its front is too faint to be seen in STEREO A COR2 and is partially obscured by the pylon in SOHO LASCO C3.

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

CME Analysis M2M_CATALOG LE true Plane-of-sky NONE 9.0 420.0 S 24.0 2024-01-12T20:33Z Because the front of this faint CME is only well seen in SOHO LASCO C2 coronagraph and the source is likely backsided, only plane-of-sky analysis was performed for this CME.
