Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2026-01-07T04:23Z ( STEREO A: SECCHI/COR2 )
All Detecting Spacecrafts:
STEREO A: SECCHI/COR2
SOHO: LASCO/C2
SOHO: LASCO/C3
GOES: CCOR-1
Activity ID: 2026-01-07T04:23:00-CME-001 (version 2)

Active Region Number: 14334
Note Keyword:
DFL: Likely deflection of the event within the FOV
Faint: Faint event; may affect type assignment

Source Signature Keyword:
FLR: Flare
FIL: Filament eruption
Morphology Keyword:
Note: CME first seen to the ESE in STEREO A COR2 starting around 2026-01-07T04:23Z. The exact start time is somewhat unclear due to imagery quality. This CME is also seen in to the SE in SOHO LASCO C2/C3 and GOES CCOR-1. The leading edge of the CME is extremely faint and difficult to see in white light imagery. The source of this CME is likely associated with one of a series of eruptions from AR 14334. The eruption beginning around 2026-01-07T03:00Z associated with a C2.9 flare from AR 14334 (S15E18) that peaked at 2026-01-07T03:54Z is the most likely source candidate. The eruptive behavior, including some filamentary structure, and flare can be see across SDO wavelengths but are best seen in SDO AIA 131 and SDO AIA 304. There appears to be some deflection possibly due to the southern extension of coronal hole W of AR 14334 that was centered approximately around S18E05 at the time of the eruption.

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 |
