Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2026-08-25T14:53Z ( STEREO A: SECCHI/COR2 )
All Detecting Spacecrafts:
STEREO A: SECCHI/COR2
Activity ID: 2026-08-25T14:53:00-CME-001 (version 1)
Note Keyword:
GAP: Data gap
OVR: Event partially overlaps with another CME
Source Signature Keyword:
BR: Brightening
Morphology Keyword:
Note: CME first seen to the E in STEREO A COR2 starting at 2026-08-25T14:53Z. This CME is not seen in GOES CCOR-1 (likely because it is nose-on) and is covered by a real-time data gap in SOHO LASCO C2/C3. The source is possibly related to some brightening along a filament channel (N12W00) between AR 14513 and AR 14517. This CME partially overlaps with outflow following CME: 2026-08-25T10:38Z and CME: 2026-08-25T12:53Z.
