Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2025-09-19T04:53Z ( SOHO: LASCO/C2 )

All Detecting Spacecrafts:

SOHO: LASCO/C2

SOHO: LASCO/C3

STEREO A: SECCHI/COR2

GOES: CCOR-1

Activity ID: 2025-09-19T04:53:00-CME-001 (version 1)

Note Keyword:

Faint: Faint event; may affect type assignment

Source Signature Keyword:

Morphology Keyword:

O: Other

Note: CME observed to the NE in SOHO LASCO C2/C3, GOES CCOR-1, and STEREO A COR. This CME has no observable source in GOES SUVI or STEREO A EUVI. The CME front appears to materialize close to the occulting disk in LASCO C2 and STEREO A COR2 and widen as it travels.
