Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2025-05-23T06:24Z ( SOHO: LASCO/C2 )
All Detecting Spacecrafts:
SOHO: LASCO/C2
SOHO: LASCO/C3
STEREO A: SECCHI/COR2
GOES: CCOR-1
Activity ID: 2025-05-23T06:24:00-CME-001 (version 1)
Note Keyword:
OVR: Event partially overlaps with another CME
PRM: Prominence material (filamentary structures)
Source Signature Keyword:
FIL: Filament eruption
Morphology Keyword:
F: Flux Rope
Note: CME first seen to the NE in SOHO LASCO C2 starting at 2025-05-23T06:24Z. Also seen to the NE in SOHO LASCO C3, STEREO A COR2, and GOES CCOR-1. This CME partially overlaps with continued outflow and rising loops at the back of CME: 2025-05-22T15:36Z. The source of this CME is most likely a filament eruption on or near the NE limb best seen in SDO AIA 304 beginning around 2025-05-23T05:00Z. The prominence can be seen building over the NE limb for several hours prior to its eruption.
