Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2025-10-31T18:23Z ( STEREO A: SECCHI/COR2 )
All Detecting Spacecrafts:
STEREO A: SECCHI/COR2
Activity ID: 2025-10-31T18:23:00-CME-001 (version 2)
Note Keyword:
DPL: CME exhibits dimpled front
Faint: Faint event; may affect type assignment
FF: Event fails/disappears before exiting COR2
OFL: Outflowing material at the back of the CME
Source Signature Keyword:
PEA: Post eruption arcade
FIL: Filament eruption
Morphology Keyword:
OS: Other and Shock Candidate
Note: CME with a fuzzy, dimpled front only seen in STEREO A COR2 coronagraph to the W and not seen in other coronagraphs. Its source is possibly a minor eruption seen behind the W limb in STEREO A EUV 195/304 starting around 2025-10-31T18:05Z as a small ejecta and minor post-eruptive arcades behind the W limb.

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 |

Approximate analysis based on the fit with all three coronagraphs (SOHO LASCO, STEREO A COR2 and GOES CCOR-1). The CME is far-sided. |

the source of this CME is behind the limb in STEREO A and the CME is not seen in any other coronagraph except for COR2, so only plane-of-sky analysis is possible. |
