Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2026-06-26T08:48Z ( SOHO: LASCO/C2 )
All Detecting Spacecrafts:
SOHO: LASCO/C2
SOHO: LASCO/C3
STEREO A: SECCHI/COR2
GOES: CCOR-1
Activity ID: 2026-06-26T08:48:00-CME-001 (version 2)
Note Keyword:
Faint: Faint event; may affect type assignment
Source Signature Keyword:
Morphology Keyword:
O: Other
Note: Faint CME observed to the W in SOHO LASCO C2/C3, GOES CCOR-1, and STEREO A COR2. The front starts very faint in LASCO C2 and develops more clearly further into the respective coronagraphs' field-of-view. The source is faint but likely field line movement and brightening from former AR 14468 observed in STEREO A EUVI 195 at 2026-06-26T05:35Z, and subtly over the NW limb in SDO AIA 193 around ~2026-06-26T05:30Z.
