Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2026-06-18T06:24Z ( SOHO: LASCO/C2 )
All Detecting Spacecrafts:
SOHO: LASCO/C2
SOHO: LASCO/C3
STEREO A: SECCHI/COR2
GOES: CCOR-1
Activity ID: 2026-06-18T06:24:00-CME-001 (version 1)
Source Location: S14W100
Active Region Number: 14464
Note Keyword:
DFL: Likely deflection of the event within the FOV
PRM: Prominence material (filamentary structures)
Source Signature Keyword:
FIL: Filament eruption
OFL: Moving/Opening field lines
BR: Brightening
Morphology Keyword:
FS: Flux Rope and Shock Candidate
Note: CME observed to the W in SOHO LASCO C2/C3 and GOES CCOR-1, and faintly to the W in STEREO A COR, as the CME was directed more directly towards STEREO A. The source is far-sided, and a complex eruption between two active regions, AR 14463 (N17W97) and AR 14464 (S14W100). Starting around 2026-06-18T05:36Z, filament ejecta is observed in SDO AIA 304 erupting from AR 14463, deflecting southward towards AR 14464 which triggers a larger filament ejecta and field line movement in SDO AIA 171/304 starting around 2026-06-18T06:09Z (as such, is considered the main source of material). This is also observed in STEREO A EUVI 304 at 2026-06-18T05:45Z, and as an area of weak dimming between the regions centered ~N00W90.

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, noting the faint front perspective in STEREO A COR makes it difficult to resolve in imagery. Triangulates well deflected to ~W80 from the observed source ~W100. |
