Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2026-08-26T22:24Z ( SOHO: LASCO/C2 )

All Detecting Spacecrafts:

SOHO: LASCO/C2

Activity ID: 2026-08-26T22:24:00-CME-001 (version 2)
Source Location: N08E45
Active Region Number: 14518

Note Keyword:

Faint: Faint event; may affect type assignment

FF: Event fails/disappears before exiting COR2

Source Signature Keyword:

FLR: Flare

OFL: Moving/Opening field lines

BR: Brightening

Morphology Keyword:

Note: Faint CME first seen to the East by SOHO LASCO C2 beginning at 2026-08-26T22:24Z. This CME fades before exiting the field-of-view in C2 and is therefore not clearly seen in other coronagraphs. The source of this event is a C3.4 flare from Active Region 14518 (N07E45) and a small eruption peaking at 2026-08-26T21:40Z as seen in SDO AIA 131, 193 and 304.
