Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2026-07-07T15:12Z ( SOHO: LASCO/C2 )
All Detecting Spacecrafts:
SOHO: LASCO/C2
Activity ID: 2026-07-07T15:12:00-CME-001 (version 1)
Source Location: S11E50
Active Region Number: 14482
Note Keyword:
Faint: Faint event; may affect type assignment
FF: Event fails/disappears before exiting COR2
Source Signature Keyword:
FLR: Flare
FIL: Filament eruption
OFL: Moving/Opening field lines
DIM: Dimming
Morphology Keyword:
L: Loop
Note: Faint CME first seen to the SE by SOHO LASCO C2 beginning at 2026-07-07T15:12Z. This CME fades before exiting the field of view in SOHO LASCO C2 and is therefore not visible in other coronagraphs. The source of this event is an M4.0 flare from Active Region 14482 (S11E50) peaking at 2026-07-07T14:19Z as seen in SDO AIA 131. Dimming and field line movement is also visible in SDO AIA 171/193, along with some filament material seen in SDO AIA 304, although most of this material appears to get reabsorbed and falls back to the solar surface.
