The graph indicates the current level of risk to satellites in low earth orbit, medium earth orbit and geostationary orbit. The index is weighted towards predicting risk due to electrostatic discharge anomalies, probably mainly from internal charging. The graph shows our predictions over the past month and for the next 6 days.
These satellite risks have been predicted using the following space weather data sources:
The assessment of satellite risk is based upon the identification of magnetic storms using a forecast of the Dst space weather index. More information on the Dst forecast, and how we turn this into a satellite risk assessment.
