Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2025-03-04T21:25Z ( SOHO: LASCO/C2 )
All Detecting Spacecrafts:
SOHO: LASCO/C2
SOHO: LASCO/C3
Activity ID: 2025-03-04T21:25:00-CME-001 (version 1)
Source Location: N15W80
Note Keyword:
GAP: Data gap

Note: This CME is visible to the west/northwest in SOHO LASCO C2/C3 imagery. It is not seen in STEREO A COR2 due to a data gap starting at 2025-03-04T19:38Z. The source is likely related to an eruption visible near the northwest limb (centered near ~N15W80) starting around 2025-03-04T21:00Z as seen in SDO AIA 131, 171, 193, 304 imagery.
