Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2026-03-13T06:48Z ( SOHO: LASCO/C2 )
All Detecting Spacecrafts:
SOHO: LASCO/C2
SOHO: LASCO/C3
STEREO A: SECCHI/COR2
GOES: CCOR-1
Activity ID: 2026-03-13T06:48:00-CME-001 (version 1)
Note Keyword:
Source Signature Keyword:
OFL: Moving/Opening field lines
Morphology Keyword:
Note: CME visible to the northwest in SOHO LASCO C2/C3, GOES CCOR-1, and STEREO A COR2. The source is far-sided, and opening field lines can be seen on the west limb in STEREO A EUV 195 imagery starting around 2026-03-13T04:55Z. An associated eruption cannot clearly be seen on-disk in STEREO A EUV imagery, and the west limb of the STEREO-A facing disk is at approximately longitude W143.
