Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2026-06-04T10:00Z ( GOES: CCOR-1 )
All Detecting Spacecrafts:
GOES: CCOR-1
STEREO A: SECCHI/COR2
Activity ID: 2026-06-04T10:00:00-CME-001 (version 1)
Note Keyword:
Faint: Faint event; may affect type assignment
GAP: Data gap
PRM: Prominence material (filamentary structures)
Source Signature Keyword:
FIL: Filament eruption
Morphology Keyword:
Note: Faint CME first seen to the SW in GOES CCOR-1 starting around 2026-06-04T10:00Z. This front is also seen to the SW in STEREO A COR2 but was missed by SOHO LASCO C2/C3 in real time due to a downlink gap. The source is most likely some ejecta seen leaving the western limb in GOES SUVI 304 beginning around 2026-06-04T08:52Z. This is one in an hours long series of similar eruptions.
