Region 14547 decayed to a plage on 2026-10-08 and rotated off of the Earth-facing disk early on 2026-10-09. This flare may be occulted due to its location near the west limb.

A minor faint CME seen to the NE in GOES CCOR-1 and SOHO LASCO C3, and not seen in STEREO A COR2 coronagraph. No source has been found in EUV imagery for this CME, so it is likely far-sided.

Data: NASA Community Coordinated Modeling Center (CCMC), DONKI; analyses by the Moon to Mars Space Weather Analysis Office. Last successful refresh: 16 Oct 2026, 00:51 EDT.
- DONKI information is supplied for research and analysis. It is not an operational emergency-warning service: NOAA's Space Weather Prediction Center (swpc.noaa.gov) is the official US source of space weather forecasts and warnings.
- Observations, analyses (a CME can have several, with the one DONKI marks most accurate), model predictions (WSA-ENLIL) and notifications are shown as such, in their original units and classifications. No combined severity score is computed.
- Times are UTC as supplied. DONKI revises entries; the look-back window is re-read on every refresh.
