All Detecting Spacecrafts:
GOES: CCOR-1
Activity ID: 2026-08-17T18:45:00-CME-001 (version 2)
Source Location: N12W65
Active Region Number: 14510

Note: This CME is visible to the northwest in GOES CCOR-1 imagery. This event is not visible in SOHO LASCO C2/C3 or STEREO A COR2 imagery in real-time. The source is likely related to a C2.0 flare from Active Region 14510 (N12W65) starting around 2026-08-17T17:00Z as seen in SDO AIA 131/171/193/304, GOES SUVI 131/171/195/284/304, and STEREO A EUVI 195/304 imagery. A subsequent opening of field lines is visible over the northeast limb in GOES SUVI 284 imagery at this time.
