Data: NASA Community Coordinated Modeling Center (CCMC), DONKI; analyses by the Moon to Mars Space Weather Analysis Office. Last successful refresh: 12 Nov 2026, 19:01 EST.
- 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.
