Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2025-06-02T12:48Z ( SOHO: LASCO/C2 )

All Detecting Spacecrafts:

SOHO: LASCO/C2

SOHO: LASCO/C3

Activity ID: 2025-06-02T12:48:00-CME-001 (version 2)

Note Keyword:

Faint: Faint event; may affect type assignment

GAP: Data gap

Source Signature Keyword:

Morphology Keyword:

L: Loop

Note: The more western, faint lobe of the CME: 2025-06-13T:25Z. The front of this faint western lobe is very faintly seen only in SOHO LASCO C3 coronagraph (mostly in running difference imagery), while it is covered by the data gap in STEREO A COR2. Not clearly seen in GOES: CCOR-1.
