2 WSA-ENLIL-Cone Modeling System  Observationally driven, near-real time modeling system  Routine simulation of corotating streams and CMEs, event-by event  Much faster than real-time

3 ENLIL Solar Wind Prediction – helioweather.net Experimental, real-time simulation of corotating and transient solar wind disturbances driven by various coronal models. Results are updated daily and are used for validation of a research ENLIL version. MODELS – Daily updated results by various driving coronal models (1.7 AU): MISSIONS – Daily updates results to support heliospheric missions (5.3 AU): ARCHIVE – Animations and temporal profiles in 2011-2014 (in progress): EVENTS – selected CME events simulated in higher resolution and presented with more details IPSBDIPSBD-SWRCWSAdub-SWRCWSAduz-SWRCWSAdtb-SWRC JUNOMAVENMESSENGERROSETTASPITZERSTEREO-ASTEREO-B

23 Summary  Routine simulations up to 5 AU are possible by 3D numerical MHD code ENLIL driven by either WSA-Cone or IPSBD coronal data at 0.1 AU  NASA/GSFC Space Weather Research Center (SWRC) operationally fits geometric and kinematic parameters of all observed CMEs: - 37 CMEs in 2014 Sep (9 CMEs > 800 km/s) - 17 CMEs in 2014 Oct (4 CMEs > 800 km/s)  HelioWeather testbed system provides results from various model variants at Earth and at various heliospheric missions. Predicted disturbances at Rosetta in 2014 Sep-Oct: - complex scenarios involves CMEs overtaken by CIRs - 11 ICMEs: 6 without shock, 5 with shocks (see Table) - 2 SEP events (Sep 1-3, Oct 10-11), other possible (see Figures)  Actual state and predictions: http://helioweather.com/missions/rosettahttp://helioweather.com/missions/rosetta  Further calibration and validation needed
