Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2026-06-11T09:48Z ( SOHO: LASCO/C2 )
All Detecting Spacecrafts:
SOHO: LASCO/C2
STEREO A: SECCHI/COR2
Activity ID: 2026-06-11T09:48:00-CME-001 (version 1)
Source Location: N12E28
Active Region Number: 14465
Note Keyword:
Faint: Faint event; may affect type assignment
Source Signature Keyword:
FLR: Flare
BR: Brightening
DIM: Dimming
EUVW: EUV Wave
Morphology Keyword:
O: Other
Note: Faint, thin CME observed to the NE in SOHO LASCO C2 and STEREO A COR2. The source is likely associated with a C9.0 flare (N10E34) from AR 14465 peaking at 2026-06-11T08:28Z, and a larger area of dimming centered nearby (N12E28) observed in SDO AIA 193 triggered with the flare.
