Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2025-07-30T03:36Z ( SOHO: LASCO/C2 )
All Detecting Spacecrafts:
SOHO: LASCO/C2
SOHO: LASCO/C3
STEREO A: SECCHI/COR2
GOES: CCOR-1
Activity ID: 2025-07-30T03:36:00-CME-001 (version 2)
Note Keyword:
DFL: Likely deflection of the event within the FOV
OVR: Event partially overlaps with another CME
Source Signature Keyword:
FLR: Flare
FIL: Filament eruption
Morphology Keyword:
Note: CME first seen to the W in SOHO LASCO C2 starting at 2025-07-30T03:36Z. CME is also seen to the W in SOHO LASCO C3, STEREO A COR2, and GOES CCOR-1. The source of this CME is most likely an eruption from on/near the W limb ~N10 beginning around 2025-07-29T22:04Z best seen in SDO AIA 304. The eruption is associated with a C3.7 flare from N09W90 that peaked at 2025-07-29T22:05Z. There is likely some southward deflection as the CME is centered about S08 once it is seen coronagraph imagery. This CME may partially overlap with CME: 2025-07-30T04:00Z.
