Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2025-07-30T04:00Z ( SOHO: LASCO/C2 )
All Detecting Spacecrafts:
SOHO: LASCO/C2
Activity ID: 2025-07-30T04:00:00-CME-001 (version 2)
Source Location: S05W35
Note Keyword:
FF: Event fails/disappears before exiting COR2
OVR: Event partially overlaps with another CME
Source Signature Keyword:
DIM: Dimming
Morphology Keyword:
Note: CME first seen to the WSW in SOHO LASCO C2 only starting around 2025-07-30T04:00Z. The most likely source candidate is a small eruption and dimming centered near S05W35 starting around 2025-07-30T03:00Z as seen in SDO AIA 131, 171, 193, 304 imagery. Another, less likely source candidate is an eruption from AR 4155 (S09W12) starting around 2025-07-30T03:30Z as seen in SDO AIA 131, 171, 193, 304 imagery. This CME fails before leaving the FOV of SOHO LASCO C2 and may partially overlap with CME: 2025-07-30T03:36Z.
