Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2026-07-03T20:00Z ( SOHO: LASCO/C2 )
All Detecting Spacecrafts:
SOHO: LASCO/C2
SOHO: LASCO/C3
GOES: CCOR-1
Activity ID: 2026-07-03T20:00:00-CME-001 (version 1)
Source Location: S10W53
Active Region Number: 14478
Note Keyword:
Source Signature Keyword:
FLR: Flare
Morphology Keyword:
F: Flux Rope
Note: Narrow CME seen to the east in SOHO LASCO C2, faintly in GOES CCOR-1, and not well at all in STEREO A due to a data gap. The CME is likely associated with the M6.3-class solar flare from Active Region 14478 occurring near S10W53 with a narrow jet of plasma being seen erupting near the active region best in SDO AIA 131 and a large loop structure leaving the southwest limb in GOES SUVI 284 near 2026-07-03T19:00Z.
