Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2026-07-09T21:00Z ( SOHO: LASCO/C2 )
All Detecting Spacecrafts:
SOHO: LASCO/C2
SOHO: LASCO/C3
GOES: CCOR-1
Activity ID: 2026-07-09T21:00:00-CME-001 (version 1)
Source Location: N15W50
Active Region Number: 14484
Note Keyword:
GAP: Data gap
Source Signature Keyword:
OFL: Moving/Opening field lines
Morphology Keyword:
Note: This CME is visible to the northwest in SOHO LASCO C2/C3 and GOES CCOR-1 imagery. This event is not visible in STEREO A COR2 due to a data gap from 2026-07-09T14:53Z to 2026-07-09T23:53Z. The source may be related to an eruption from Active Region 14484 (N15W50) starting around 2026-07-09T20:45Z as seen in SDO AIA 131/193/304 and GOES SUVI 131/195/284/304 imagery. A subsequent opening of field lines is visible over the northwest limb at this time in SDO AIA 193 and GOES SUVI 284 imagery as well.
