Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2025-05-20T21:12Z ( SOHO: LASCO/C2 )
All Detecting Spacecrafts:
SOHO: LASCO/C2
SOHO: LASCO/C3
GOES: CCOR-1
Activity ID: 2025-05-20T21:12:00-CME-001 (version 1)
Note Keyword:
Faint: Faint event; may affect type assignment
GAP: Data gap
Source Signature Keyword:
OFL: Moving/Opening field lines
Morphology Keyword:
Note: Faint and narrow CME to the east in SOHO LASCO C2, C3, and GOES CCOR-1. Not visible in STEREO A COR2 due to a data gap from 2025-05-20T17:09Z to 2025-05-21T01:23Z. Source is possibly beyond the eastern limb based on field line movement starting around 2025-05-20T20:00Z as seen in GOES SUVI 284. An additional potential source includes minor movement from AR 14093 (~S06E65) as seen in available SDO/AIA imagery.
