Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2026-02-03T19:00Z ( SOHO: LASCO/C2 )
All Detecting Spacecrafts:
SOHO: LASCO/C2
SOHO: LASCO/C3
STEREO A: SECCHI/COR2
GOES: CCOR-1
Activity ID: 2026-02-03T19:00:00-CME-001 (version 2)
Source Location: N10W30
Note Keyword:
GAP: Data gap
Source Signature Keyword:
FIL: Filament eruption
DIM: Dimming
Morphology Keyword:
Note: This CME is visible to the west/northwest in SOHO LASCO C2/C3 and GOES CCOR-1 imagery. This event is visible to the northeast in STEREO A COR2 imagery following a data gap that ends at 2026-02-04T03:23Z. The source may be related to a slow-to-lift off filament eruption starting around 2026-02-03T15:00Z which spans ~N20W30 to ~N00W45 as seen in SDO AIA 193/304 imagery. A subsequent dimming is observed in SDO AIA 193 imagery around this time which appears to move westward.
