Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2026-07-18T20:12Z ( SOHO: LASCO/C2 )
All Detecting Spacecrafts:
SOHO: LASCO/C2
SOHO: LASCO/C3
STEREO A: SECCHI/COR2
GOES: CCOR-1
Activity ID: 2026-07-18T20:12:00-CME-001 (version 1)
Source Location: S08W105
Active Region Number: 14482
Note Keyword:
COL: Possible collision with previous CME
OVR: Event partially overlaps with another CME
Source Signature Keyword:
FIL: Filament eruption
OFL: Moving/Opening field lines
BR: Brightening
Morphology Keyword:
F: Flux Rope
Note: CME observed to the W in SOHO LASCO C2/C3, GOES CCOR-1, and STEREO A COR2. This front quickly overtakes prior faint CME: 2026-07-18T19:36Z. The source of this CME is former AR 14482, observed best in STEREO A EUVI 195/304 as filament ejecta and brightening around approximately S08W105, starting around 2026-07-18T19:25Z. The eruption is observed over the West limb in SDO AIA 171/193/304 and GOES SUVI 171/195/284/304 as field line movement and the filament ejecta.
