Corotating Model: Real-time forecast of the solar wind at Earth Shown are time series of the interplanetary magnetic field near Earth derived from the corotating tomography model (solid curve) in comparison with Advanced Composition Explorer (ACE) spacecraft data (dashed curve). The 'root-mean-square' residual difference between the two time series is indicated. Radial magnetic field is to the left; tangential magnetic field is to the right. The display is updated hourly, most recently at (insert system time here) as indicated by the vertical dashed line. ACE data are usually available up to this time; the corotating model forecasts several days past this time into the future. The model is updated every time new data are received from STELab, Japan (most recently at (insert t3d_time here)) and is the same curve as shown at the bottom of the corotating model synoptic forecast map plotted with time increasing left to right. The animations run in (insert movie time step here) steps from (insert begin movie here) before, to (insert end movie here) after the last time data were received.
