Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2026-06-18T00:00Z ( SOHO: LASCO/C2 )
All Detecting Spacecrafts:
SOHO: LASCO/C2
SOHO: LASCO/C3
GOES: CCOR-1
Activity ID: 2026-06-18T00:00:00-CME-001 (version 1)
Source Location: N17W96
Active Region Number: 14463
Note Keyword:
PRM: Prominence material (filamentary structures)
Source Signature Keyword:
FIL: Filament eruption
Morphology Keyword:
Note: CME first seen to the WNW in SOHO LASCO C2 starting around 2026-06-18T:00Z. It is also seen to the WNW in SOHO LASCO C3 and GOES CCOR-1 but is not seen in STEREO A COR2. The source of this CME is most likely a small filament eruption from beyond the NW limb best seen in SDO AIA 304 beginning around 2026-06-17T23:24Z, likely from former AR 14463 (N17W96).

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.
