This site presents results from a research version of the heliospheric code ENLIL for the Parker Solar Probe mission since its launch. The 3-D MHD computations were performed on a numerical grid with the 2-deg angular spacing and they used the WSA coronal maps and CME parameters calculated and fitted at NASA/CCMC. The stable ENLIL version is used by NOAA/SWPC and UK MetOffice for official space weather forecast and by NASA/CCMC for run-on-request support of the space weather community and for operational support of NASA heliospheric and other missions.
Global and detail views of the solar wind radial velocity at ecliptic and predicted values at the spacecraft. Projected spacecraft positions use acronyms: BEP=BepiColombo, HAY=Hayabusha-2, PSP=Parker Solar Probe, SOL=Solar Orbiter, SPI=Spitzer, STA=STEREO-A, STB=STEREO-B. On the temporal profile, the light-green (yellow) shading indicates a range of predicted values at latitudinal positions by two (four) deg apart from the spacecraft position.
Global view of the normalized solar wind density at ecliptic. Projected spacecraft positions use acronyms as given above.
Heliospheric disturbances shown on two panels. Left panel shows the normalized solar wind density at the ecliptic plane together with the combined field of views (FOVs) of the Parker Solar Probe detectors (dashed lines), elongations at 20, 40, and 60 deg (solid lines), and planetary positions. Right panel shows the running difference (2h cadence) of synthetic white-light total brightness images viewed from Parker Solar Probe together with an approximate outline of the FOVs of its WISPR detectors shown by dashed lines (smaller and larger rectangular ones for the Inner and Outer detector, respectively), elongations at 20, 40, and 60 deg (solid lines), and planetary positions.
