Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2025-11-15T22:36Z ( SOHO: LASCO/C2 )
All Detecting Spacecrafts:
SOHO: LASCO/C2
SOHO: LASCO/C3
GOES: CCOR-1
Activity ID: 2025-11-15T22:36:00-CME-001 (version 1)
Source Location: N45W20
Note Keyword:
Faint: Faint event; may affect type assignment
GAP: Data gap
OFL: Outflowing material at the back of the CME
OVR: Event partially overlaps with another CME
Source Signature Keyword:
PEA: Post eruption arcade
FIL: Filament eruption
DIM: Dimming
Morphology Keyword:
FS: Flux Rope and Shock Candidate
Note: CME directed NNW in SOHO and GOES CCOR-1 coronagraphs, with two consecutive fronts (either a shock and a bulk or two consecutive CMEs). Source is likely a filament eruption centered at (N45W20) seen as dimming and significant area of post-eruptive arcades centered around this area in GOES SUVI 195, and as slowly rising northern ejecta in SUVI 304 seen after 2025-11-15T21:20Z. The erupting filament seems to be ~30-40 degrees in length.

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 |

A tentative analysis with one coronagraph (SOHO LASCO), based on a very approximate source location (N45W20). In the absence of STEREO A imagery due to long data gap this is the best that can be done. |

Approximate analysis of the second front of this CME (likely its bulk) with one coronagraph analysis method (using SOHO) and based on the approximate location of the source - an erupting 30-40 long northern filament. STEREO A imagery is not available for this event. |
