Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2026-03-13T06:24Z ( SOHO: LASCO/C2 )
All Detecting Spacecrafts:
SOHO: LASCO/C2
SOHO: LASCO/C3
STEREO A: SECCHI/COR2
Activity ID: 2026-03-13T06:24:00-CME-001 (version 1)
Source Location: N25E20
Note Keyword:
OVR: Event partially overlaps with another CME
Source Signature Keyword:
OFL: Moving/Opening field lines
DIM: Dimming
Morphology Keyword:
Note: CME visible to the N/NE in SOHO LASCO C2/C3 and GOES CCOR-1. The CME overlaps in the field of view with CME: 2026-03-13T06:48Z in these coronagraphs. The CME is also visible to the NE in STEREO A COR2. There is at least one potential source eruption on the Earth-facing disk as seen in GOES SUVI 195 and 284 imagery, starting around 2026-03-13T05:44Z as dimming centered around N35W20. Additional dimming can be seen starting around the same time, centered around N25E20, and this is the more likely source candidate.

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.
