Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2026-09-06T10:53Z ( STEREO A: SECCHI/COR2 )
All Detecting Spacecrafts:
STEREO A: SECCHI/COR2
Activity ID: 2026-09-06T10:53:00-CME-001 (version 1)
Source Location: N12E32
Active Region Number: 14524
Note Keyword:
GAP: Data gap
Source Signature Keyword:
FLR: Flare
DIM: Dimming
EUVW: EUV Wave
Morphology Keyword:
Note: This CME is visible to the east in STEREO A COR2 imagery only. This event is not seen in SOHO LASCO C2/C3 or GOES CCOR-1 in real-time due to data gaps starting around 2206-09-06T03:30Z. The source is an eruption and C5.0 flare from Active Region 14524 (N12E32) starting around 2026-09-06T10:36Z as seen in SDO AIA 131/171/193/304, GOES SUVI 131/171/195/284/304, and STEREO A EUVI 304 imagery. An EUV wave and subsequent dimming is observed moving south of the eruption site, seen in SDO AIA 193 and GOES SUVI 195 imagery.
