Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2026-04-01T03:00Z ( SOHO: LASCO/C2 )
All Detecting Spacecrafts:
SOHO: LASCO/C2
Activity ID: 2026-04-01T03:00:00-CME-001 (version 1)
Source Location: N20W11
Active Region Number: 14403
Note Keyword:
DFL: Likely deflection of the event within the FOV
Faint: Faint event; may affect type assignment
CHP: CME - Coronal Hole Proximity
Source Signature Keyword:
FIL: Filament eruption
OFL: Moving/Opening field lines
BR: Brightening
Morphology Keyword:
O: Other
Note: Faint CME observed to the NW in SOHO LASCO C2, possibly too faint or not yet seen in other available coronagraph imagery and/or blocked by the GOES CCOR-1 Earth eclipse. The source is an eruption from AR 14403 starting around 2026-04-01T02:03Z in SDO AIA 171/193/304 as brightening centered around N20W11, field line movement, and filament ejecta extending narrowly up to the NE from the eruption, appearing to largely dissipate or reabsorb to the disk. Also seen in STEREO A EUVI 195/304 as the same brightening, field line movement, and filament ejecta.

3D SOHO LASCO C2 only analysis, using the W11 source longitude, finding a further southern latitude than expected. With the filement ejecta poorly erupting and coronal hole proximity, deflection is likely, and the lack of a visible front in STEREO A COR2 means no triangulation possible. |
