Catalog: M2M_CATALOG
Start Time: 2026-09-07T01:48Z ( SOHO: LASCO/C2 )
All Detecting Spacecrafts:
SOHO: LASCO/C2
SOHO: LASCO/C3
STEREO A: SECCHI/COR2
GOES: CCOR-1
Activity ID: 2026-09-07T01:48:00-CME-001 (version 1)

OFL: Moving/Opening field lines
Morphology Keyword:
Note: This CME is visible to the east in SOHO LASCO C2/C3 and GOES CCOR-1 imagery, and to the west in STEREO A COR2 imagery. The source is far-sided and likely related to an opening of field lines visible over eastern limb in SDO AIA 171/193 and GOES SUVI 171/195/284 imagery starting around 2026-09-07T00:50Z.
