The browser ate my homework. Long story short:

Space Weather Prediction Center
National Oceanic and Atmospheric Administration
Relativistic Electron Forecast Model

Quote:
The REFM plot displays roughly 30 days of observed and forecast data. Previous forecast values are kept on screen for comparison with observed data. Plot symbols correspond to the 24-hour >2 MeV electron fluence at geo-synchronous orbit, either observed or forecast. The forecasted and observed fluence values for the most recently observed 24-hour period is indicated by the dashed vertical lines. The 1, 2, and 3-day forecasts are to the right of the dashed vertical lines. A legend in the lower left corner indicates the symbol and color-coding used for the observed and forecast values. The lower right corner contains the latest observed and 1-3 day forecast values in a tabular format. The values are also color-coded in the same manner as the plot symbols. The date shown is valid at the beginning of the 24-hour period. When the 72-hour fluence exceeds 109 (cm2 s sr)-1, a warning message is displayed. Red lines (solid for observed and dashed for forecast) appear at the top of the plot, corresponding to the applicable days. A warning message also appears in the legend.
If there are electric-impenetrable barriers dividing the layers named in Latin, why the red color?
