Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2026-05-02T11:24Z ( SOHO: LASCO/C2 )
All Detecting Spacecrafts:
SOHO: LASCO/C2
SOHO: LASCO/C3
STEREO A: SECCHI/COR2

Activity ID: 2026-05-02T11:24:00-CME-001 (version 1)

DFL: Likely deflection of the event within the FOV

FLR: Flare
FIL: Filament eruption
Morphology Keyword:
Note: CME first seen to the WNW in SOHO LASCO C2 starting at 2026-05-02T11:24Z. It is also seen to the WNW in SOHO LASCO C3, GOES CCOR-1, and faintly for a couple frames in STEREO A COR2. The source of this CME is most likely a filament eruption centered around N16W75 to the W of AR 14424. The eruption is best seen in SDO AIA 304 and STEREO A SUVI 304 beginning around 2026-05-02T10:48Z. The eruption is also associated with a C4.0 flare that peaked at 2026-05-02T11:04Z and was centered around N16W75. There appears to be some minor southward deflection later in the propagation of the CME. There is likely also some westward deflection due to the proximity to a coronal hole that was centered at approximately N33W30 at the time of the eruption.

There is some degree of uncertainty in this measurement because this CME is partially obscured by a brighter CME in STEREO A COR2. 1: Result 1 (2.0 AU)
