Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2024-02-12T03:36Z ( SOHO: LASCO/C2 )

All Detecting Spacecrafts:

SOHO: LASCO/C2

SOHO: LASCO/C3

STEREO A: SECCHI/COR2

Activity ID: 2024-02-12T03:36:00-CME-001 (version 1)

Note Keyword:

COL: Possible collision with previous CME

Faint: Faint event; may affect type assignment

FF: Event fails/disappears before exiting COR2

OVR: Event partially overlaps with another CME

Source Signature Keyword:

Morphology Keyword:

LS: Loop and Shock Candidate

Note: Faint CME to the east in coronagraphs that overtakes a previous even fainter and much slower eastern CME. No clear source was found in EUV imagery. There is a very minor loop from behind the E limb seen in SUVI 171 around 2022-02-12T01:36Z but it seems too minor. Alternatively, there is a relatively faint but large in area dimming near the coronal hole in the east starting around 2024-02-11T23:45Z and centered very approximately around S01E20, however frontsided longitude does not produce a fit in swpc_cat.
