Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2026-06-18T01:28Z ( SOHO: LASCO/C2 )
All Detecting Spacecrafts:
SOHO: LASCO/C2
Activity ID: 2026-06-18T01:28:00-CME-001 (version 2)
Source Location: S14W100
Active Region Number: 14464
Note Keyword:
DFL: Likely deflection of the event within the FOV
Faint: Faint event; may affect type assignment
OVR: Event partially overlaps with another CME
Source Signature Keyword:
FIL: Filament eruption
OFL: Moving/Opening field lines
BR: Brightening
Morphology Keyword:
O: Other
Note: Faint CME observed to the W in SOHO LASCO C2 before it is overtaken by brighter CME: 2026-06-18T02:36Z. The source is likely former AR 14464, located ~S14W100, observed as a small deflecting filament ejecta and field line movement over the SW limb in GOES SUVI 171/304 starting around 2026-06-18T00:16Z.
