ENLIL Solar Wind Prediction – Rosetta

Rosetta was a space probe launched on 2004-03-02 to performed a detailed study of comet 67P/Churyumov-Gerasimenko (67P). During its journey to the comet, the spacecraft performed flybys of Earth, Mars, and the asteroids 21 Lutetia and 2867 Steins. The last contact with the spacecraft was on 2016-09-30.

This site presents results from a research version of the heliospheric code ENLIL for the Rosetta 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.
