Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2026-03-07T10:38Z ( STEREO A: SECCHI/COR2 )
All Detecting Spacecrafts:
STEREO A: SECCHI/COR2
Activity ID: 2026-03-07T10:38:00-CME-001 (version 1)
Note Keyword:
Faint: Faint event; may affect type assignment
FF: Event fails/disappears before exiting COR2
OFL: Outflowing material at the back of the CME
OVR: Event partially overlaps with another CME
Source Signature Keyword:
Morphology Keyword:
J: Jet
Note: A faint and narrow CME front seen to the SE in COR2A. The source is likely far-sided, possibly indicated by the minor movement of field lines seen in GOES SUVI 195 on/behind the SE limb after 2026-03-07T09:30Z.

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. This is a helpful flag if you would like to download only one most accurate CME analysis per CME per Measurement Type

CME Analysis M2M_CATALOG LE true Plane-of-sky NONE -15.0 540.0 C 10.0 2026-03-07T16:09Z This minor CME is only seen in STEREO A COR2 and not seen in other coronagraphs. The source is likely far-sided, therefore only plane-of-sky analysis is possible for this event. Not modeled Anna Chulaki on 2026-03-07T18:41Z
