Forecasting space weather is of vital importance in protecting NASA assets around the solar system. For this reason, NASA routinely tests various space weather models at the Community-Coordinated Modeling Center (CCMC).

This visualization is constructed from a computer model run of a coronal mass ejection (CME) launched from the sun in early March, 2012. The preliminary CME parameters were measured from instruments on the STEREO (the red and blue satellite icons) and SDO (in Earth orbit) satellites. The Enlil model was used to propagate those parameters through the solar system. From this model, they can estimate the strength and time of arrival of the CME at various locations around the solar system. This allows other missions to either safe-mode their satellites for protection, or allow them to conduct measurements to test the accuracy of the model.

Enlil model for the March 2012 coronal mass ejection, plotted out to ten astronomical units (beyond the orbit of Saturn). The top view slices the data in the plane of the Earth's orbit and projects the planetary orbits onto that. The side view is a cross-section through the Sun-Earth line. The wedge-shape of the side view is because the Enlil model only extends above and below the solar equator by 60 degrees.

This color table represents how displaying each of the three variables as separate red, green, and blue color ramps combine to identify characteristics in the solar wind and CME.
