Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2025-11-13T01:36Z ( SOHO: LASCO/C2 )
All Detecting Spacecrafts:
SOHO: LASCO/C2
SOHO: LASCO/C3
STEREO A: SECCHI/COR2
Activity ID: 2025-11-13T01:36:00-CME-001 (version 1)
Note Keyword:
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:
L: Loop
Note: Extremely faint CME seen to the NW in SOHO LASCO C2 and STEREO A COR2 but too faint in C3 and GOES CCOR-1. Its source may potentially be the minor eruption in AR 4274 (N24W51), directed northward and seen in GOES SUVI 304 at 2025-11-13T01:15Z, however the fit with two coronagraphs indicates that the CME is far-sided.

Prime?"primary flag" which is either True or False. If there are multiple CME analysis entries for a single CME, this flag would indicate which analysis is considered most accurate per measurement type.

CME Analysis M2M_CATALOG LE true SWPC_CAT 116.0 33.0 553.0 C 37.0 2025-11-13T08:11Z Analysis based on the fit with two coronagraphs indicates the source should be behind the NW limb, however no source has been found in STEREO A EUV imagery to confirm this fit. Because of the extreme faintness of the CME and the lack of coronal signatures these parameters are rather speculative. Not modeled Anna Chulaki on 2025-11-13T18:46Z
