• Results of heliospheric simulations are shown as evolution of parameters at Earth, planets, and spacecraft.
• Date (in UTC) at the top center corresponds to the beginning of computations.
• Plots from top to down show the radial component of the flow velocity, plasma number density, mean temperature, and magnetic field strength.
• Black lines show profiles at the location of Earth, planets, and spacecraft (actual location name is indicated at the top right).
• Vertical black line indicates beginning of the new prediction which is always at the beginning of the calendar date (UTC). Note that a single, corotating map is used to drive the heliospheric simulations for -/+ day span about that beginning. Values to the left (right) from the vertical black line thus represents "historic" ("prediction") results.
• Vertical black dashed line indicates date of the GONG observation file used to calculate WSA input data. Note that the heliospheric computation uses available WSA input data collected during the first day since the beginning of the heliospheric computations.
• Observations, if available, are shown by color symbols. Note that the plot is generated after the heliospheric simulation is finished; thus the observations may cover one day after the beginning date of the heliospheric simulation (indicated by the vertical black line).
