Catalog: M2M_CATALOG
Start Time: 2026-09-04T21:45Z ( GOES: CCOR-1 )
All Detecting Spacecrafts:
GOES: CCOR-1
STEREO A: SECCHI/COR2
Activity ID: 2026-09-04T21:45:00-CME-001 (version 1)
Note Keyword:
DFL: Likely deflection of the event within the FOV
DPL: CME exhibits dimpled front
GAP: Data gap
Source Signature Keyword:
FIL: Filament eruption
Morphology Keyword:
Note: This CME is visible to the NE in GOES CCOR-1 and STEREO A COR2 imagery. There is a real-time DSN gap in the SOHO LASCO data covering the timing of this event. The source of this CME is an eruption from beyond the E/NE limb with visible deflection to the NE starting around 2026-09-04T20:52Z as seen in GOES SUVI 304.
