All Detecting Spacecrafts:
STEREO A: SECCHI/COR2
GOES: CCOR-1
Activity ID: 2026-01-29T12:45:00-CME-001 (version 2)
Note Keyword:
Faint: Faint event; may affect type assignment

Note: CME first seen to the SSE by GOES CCOR-1 beginning at 2026-01-29T12:45Z, as well as to the SSW in STEREO A COR2 in later frames. This CME is not visible in SOHO LASCO C2/C3 in real time due to a downlink data gap which began at 2026-01-29T08:24Z. The source of this event is field line opening seen beyond the SE limb in SDO AIA 171 beginning around 2026-01-29T11:10Z.
