Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2026-09-13T01:24Z ( SOHO: LASCO/C2 )
All Detecting Spacecrafts:
SOHO: LASCO/C2
SOHO: LASCO/C3
Activity ID: 2026-09-13T01:24:00-CME-001 (version 1)
Note Keyword:
PRM: Prominence material (filamentary structures)
Source Signature Keyword:
FIL: Filament eruption
Morphology Keyword:
Note: CME first seen to the W in SOHO LASCO C2 starting at 2026-09-13T01:24Z. It is also seen to the W in SOHO LASCO C3. This CME is mostly obscured by Earthshine in GOES CCOR-1 and is not seen in STEREO A COR2. There is no definitive source candidate, but the source may be related to some minor activity in a filament structure over the W limb best seen in GOES SUVI 304 beginning around 2026-09-13T22:30Z.
