Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2025-05-12T04:23Z ( STEREO A: SECCHI/COR2 )

All Detecting Spacecrafts:

STEREO A: SECCHI/COR2

SOHO: LASCO/C3

Activity ID: 2025-05-12T04:23:00-CME-001 (version 1)

Note Keyword:

Faint: Faint event; may affect type assignment

FF: Event fails/disappears before exiting COR2

Source Signature Keyword:

Morphology Keyword:

L: Loop

Note: A super faint loop CME seen mostly in the running difference imagery to the south-southwest in both coronagraphs (SOHO LASCO and STEREO A COR2). The start of this CME is likely hours earlier. Its front is not seen in C2 and appears in COR2A and C3 after 2025-05-12T04Z, when it is halfway through the field of view.
