Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2026-09-13T21:12Z ( SOHO: LASCO/C2 )
All Detecting Spacecrafts:
SOHO: LASCO/C2
SOHO: LASCO/C3
GOES: CCOR-1
Activity ID: 2026-09-13T21:12:00-CME-001 (version 1)
Source Location: S10W10
Note Keyword:
Faint: Faint event; may affect type assignment
GAP: Data gap
Source Signature Keyword:
OFL: Moving/Opening field lines
DIM: Dimming
Morphology Keyword:
L: Loop
Note: Faint CME first seen to the West by SOHO LASCO C2 beginning at 2026-09-13T21:12Z, as well as by SOHO LASCO C3 and GOES CCOR-1 in later frames. This event is not seen in STEREO A COR2 due to a data gap which began at 2026-09-13T19:23Z. The source of this CME is likely outflow following an earlier filament eruption beginning at 2026-09-13T18:48Z centered at approx. S10W10 as seen in SDO AIA 193 and 304. This CME is likely deflected to the NW due to proximity to a large coronal hole.
