Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2026-07-31T15:23Z ( STEREO A: SECCHI/COR2 )
All Detecting Spacecrafts:
STEREO A: SECCHI/COR2
GOES: CCOR-1
Activity ID: 2026-07-31T15:23:00-CME-001 (version 1)
Source Location: S20W35
Note Keyword:
DFL: Likely deflection of the event within the FOV
Faint: Faint event; may affect type assignment
GAP: Data gap
CHP: CME - Coronal Hole Proximity
Source Signature Keyword:
DIM: Dimming
Morphology Keyword:
O: Other
Note: Faint CME observed to the E in STEREO A COR2, and faintly to the W/NW in GOES CCOR-1. The source is likely an area of diffuse dimming centered ~S20W35, observed in SDO AIA 193 starting around 2026-07-31T12:54Z.
