Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2026-06-08T06:12Z ( SOHO: LASCO/C2 )
All Detecting Spacecrafts:
SOHO: LASCO/C2
SOHO: LASCO/C3
STEREO A: SECCHI/COR2
GOES: CCOR-1
Activity ID: 2026-06-08T06:12:00-CME-001 (version 1)
Source Location: S08E42
Active Region Number: 14464
Note Keyword:
Faint: Faint event; may affect type assignment
Source Signature Keyword:
OFL: Moving/Opening field lines
DIM: Dimming
Morphology Keyword:
O: Other
Note: Faint CME observed to the E in SOHO LASCO C2 and STEREO A COR2, even more faintly in SOHO LASCO C3/GOES CCOR-1 due to it fading into the background after early frames. The source is likely an area of field line movement and dimming centered around S08E42, near AR 14464 (S12E35) starting around 2026-06-08T04:25Z in SDO AIA 171/193.

Prime?"primary flag" which is either True or False. If there are multiple CME analysis entries for a single CME, this flag would indicate which analysis is considered most accurate per measurement type.
