Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2026-05-07T18:36Z ( SOHO: LASCO/C2 )
All Detecting Spacecrafts:
SOHO: LASCO/C2
SOHO: LASCO/C3
STEREO A: SECCHI/COR2
GOES: CCOR-1
Activity ID: 2026-05-07T18:36:00-CME-001 (version 1)

Note: This CME is visible to the northeast in SOHO LASCO C2/C3, GOES CCOR-1, and STEREO A COR2 imagery and follows in the path of CME: 2026-05-07T15:23Z. The source is likely related to an eruption starting around 2026-05-07T17:30Z from a currently unnumbered region near the northeast limb in SDO AIA 131/171/193/304 imagery. This eruption follows the M2.6 flare which peaked at 2026-05-07T15:14Z from the same region near the northeast limb, located around ~N20E110 based on Solar Orbiter EUI imagery from 2026-05-07T00:01Z.
