Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2025-06-25T04:36Z ( SOHO: LASCO/C2 )
All Detecting Spacecrafts:
SOHO: LASCO/C2
SOHO: LASCO/C3
STEREO A: SECCHI/COR2
GOES: CCOR-1
Activity ID: 2025-06-25T04:36:00-CME-001 (version 1)
Note Keyword:
Faint: Faint event; may affect type assignment
Source Signature Keyword:
OFL: Moving/Opening field lines
Morphology Keyword:
Note: CME first seen to the E in SOHO LASCO C2 starting at 2025-06-25T04:24Z. 2025-06-25T04:36Z start time chosen for distinction from previous CME. Also seen to the E in SOHO LASCO C3, GOES CCOR-1, and for a couple of frames in STEREO A COR2. The source of this CME is likely far-sided. There is some very faint field line movement from beyond the E limb best seen in SDO AIA 193 around 2025-06-25T02:30Z that could be the source of this CME.
