Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2026-06-19T03:53Z ( STEREO A: SECCHI/COR2 )
All Detecting Spacecrafts:
STEREO A: SECCHI/COR2
Activity ID: 2026-06-19T03:53:00-CME-001 (version 1)
Source Location: S40E40
Note Keyword:
Faint: Faint event; may affect type assignment
FF: Event fails/disappears before exiting COR2
Source Signature Keyword:
FIL: Filament eruption
DIM: Dimming
Morphology Keyword:
Note: Faint CME visible to the SE in STEREO A COR2. Not clearly visible in SOHO LASCO C2/C3 or GOES CCOR-1 imagery. The potential source is a filament eruption centered around S40E40 as seen in SDO AIA 304 imagery with liftoff starting around 2026-06-18T21:36Z. Dimming is also seen in SDO AIA 193 imagery. The eruption is not visible in STEREO A EUV imagery.
