Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2025-06-01T18:00Z ( SOHO: LASCO/C2 )
All Detecting Spacecrafts:
SOHO: LASCO/C2
SOHO: LASCO/C3
STEREO A: SECCHI/COR2
GOES: CCOR-1
Activity ID: 2025-06-01T18:00:00-CME-001 (version 1)
Note Keyword:
Faint: Faint event; may affect type assignment
Source Signature Keyword:
OFL: Moving/Opening field lines
Morphology Keyword:
L: Loop
Note: Faint loop CME first distinguishable as a coherent front to the SW in SOHO LASCO C2 at 2025-06-01T18:00Z. There is no clear source in available UV imagery. There are several extremely faint, outflow-like fronts seen to the SW around this time. This front is the most cohesive and is visible in SOHO LASCO C2/C3, STEREO A COR2, and GOES CCOR-1.
