Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2025-09-12T04:17Z ( SOHO: LASCO/C2 )
All Detecting Spacecrafts:
SOHO: LASCO/C2
SOHO: LASCO/C3
STEREO A: SECCHI/COR2
GOES: CCOR-1
Activity ID: 2025-09-12T04:17:00-CME-001 (version 1)
Note Keyword:
Faint: Faint event; may affect type assignment
CHP: CME - Coronal Hole Proximity
Source Signature Keyword:
FIL: Filament eruption
OFL: Moving/Opening field lines
Morphology Keyword:
O: Other
Note: Faint CME observed to the NW in SOHO LASCO C2/C3, GOES CCOR-1, and STEREO A COR2. The source is a small filament eruption likely from former AR 14212 now around the west limb as viewed from SDO AIA and GOES SUVI, but viewed directly in STEREO A EUVI. Narrow filament ejecta and field line movement over the west limb best observed in GOES SUVI 284/304 starting around 2025-09-12T02:53Z is also observed in SDO AIA 171/193/304. Brightening at the location of former AR 14212 as viewed from STEREO A in EUVI 195 at 2025-09-12T03:05Z and EUVI 304 at 2025-09-12T03:15Z are also observed for a single frame due to the instrument's lower cadence.

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 |

Triangulation between SOHO LASCO C2/C3 and STEREO A COR2 of the brighest piece of this faint front, the outermost leading edge is too faint and diffuse to track. Front becomes too faint after earliest frames. |
