Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2025-11-29T06:23Z ( STEREO A: SECCHI/COR2 )
All Detecting Spacecrafts:
STEREO A: SECCHI/COR2
SOHO: LASCO/C3
GOES: CCOR-1
Activity ID: 2025-11-29T06:23:00-CME-001 (version 1)
Note Keyword:
Faint: Faint event; may affect type assignment
FF: Event fails/disappears before exiting COR2
HAL: Halo CME
OFL: Outflowing material at the back of the CME
OVR: Event partially overlaps with another CME
Source Signature Keyword:
Morphology Keyword:
FS: Flux Rope and Shock Candidate
Note: Front seen directly N in STEREO A COR2, with no source found on the Earth-facing disk, so the likely CME longitude is -130 deg. The front is harder to ascertain in other coronagraphs, however there is a faint follow-up front following the pointy-nosed 2025-11-29T05:48Z CME, which fits well with this northern front seen in STEREO A at the longitude of -130 degrees (the likely longitude for this event).

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/speculative analysis of the bulk front of this CME, based mainly on the fact that the CME is seen directly N in STEREO A COR2, indicating the longitude of -130 degrees and also 'confirmed' by the fit of the brighter front in COR2 with the much fainter front to the NE in SOHO LASCO and GOES CCOR-1. |

A very speculative analysis of the faint full halo shock front of this CME, based on the assumption that the longitude of the CME is approximately -130 degrees (since it is seen as full halo in STEREO A). However, there are multiple other fast CMEs happening simultaneously with this (including a faster 2025-11-29T05:48Z CME), so the shock may be associated with one of these other CMEs. |
