Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2025-06-28T21:00Z ( SOHO: LASCO/C2 )
All Detecting Spacecrafts:
SOHO: LASCO/C2
SOHO: LASCO/C3
STEREO A: SECCHI/COR2
GOES: CCOR-1
Activity ID: 2025-06-28T21:00:00-CME-001 (version 1)
Source Location: N07W22
Active Region Number: 14126
Note Keyword:
Faint: Faint event; may affect type assignment
HAL: Halo CME
Source Signature Keyword:
FLR: Flare
OFL: Moving/Opening field lines
BR: Brightening
Morphology Keyword:
O: Other
Note: CME observed as a faint partial halo, nearly a full halo, directed towards the NW in SOHO LASCO C2, and a brighter front to the NE in STEREO A COR. Also faintly observed in currently available frames of SOHO LASCO C3 and GOES CCOR-1. The source is a C4.0 flare from AR 14126 (N07W22) which peaked at 2025-06-28T19:54Z observed in SDO AIA 131, alongside brightening in SDO AIA 171/193/304 and a small dimming SW of the region best seen in SDO AIA 193.
