Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2026-03-17T08:23Z ( STEREO A: SECCHI/COR2 )
All Detecting Spacecrafts:
STEREO A: SECCHI/COR2
SOHO: LASCO/C2
Activity ID: 2026-03-17T08:23:00-CME-001 (version 1)
Source Location: S05W15
Note Keyword:
Source Signature Keyword:
FIL: Filament eruption
Morphology Keyword:
Note: CME visible to the SE in STEREO A COR2. The CME may also faintly be seen to the west in early frames of SOHO LASCO C2 imagery. It is not clearly visible in GOES CCOR-1 or STEREO A COR2 imagery. The potential source is a filament eruption with liftoff seen starting around 2026-03-17T05:15Z in the southeast of STEREO A EUV 304. The filament liftoff is also visible in GOES SUVI 304 imagery, centered around S05W15.

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 |
