- 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.
