## Summary:

Ensemble modeling update on CME with ID 2017-09-10T16:09:00-CME-001 (see previous notifications 20170910-AL-006, 20170910-AL-007, 20170911-AL-001). Based on heliospheric ensemble modeling carried out at NASA GSFC Space Weather Research Center, it is estimated that the CME may impact STEREO B and Mars. For 40 ensemble members (see notes section), simulations indicate that the leading edge of the CME will reach:

- STEREO B between about 2017-09-11T15:12Z and 2017-09-12T04:35Z (average arrival 2017-09-11T21:31Z) for 100% of simulations.
- Mars between about 2017-09-13T02:02Z and 2017-09-13T22:08Z (average arrival 2017-09-13T11:18Z) for 30% of simulations.

Additionally the CME is estimated to reach NASA missions near Earth between about 2017-09-12T10:41Z and 2017-09-12T23:49Z (average arrival 2017-09-12T16:06Z) for 12% of simulations.  The ensemble-based forecast indicates that there is a 75% chance for the maximum Kp index to be in the 3-4 range (below minor).

## Notes:
Ensemble CME modeling at SWRC is performed by building sets of initial CME parameters and carrying out separate simulations for each set. This approach allows a mapping of initial CME parameter uncertainties into a statistical characterization of CME arrival times and impact at locations of interest.

Description of links: For each location, the first link shows the WSA-ENLIL+Cone model animation for the median CME input parameters, the second link shows the probabilistic distribution of predicted arrival times histogram, and the third link shows a stack plot of the WSA-ENLIL+Cone modeled magnetic field, velocity, density, and temperature for all ensemble members. For missions near Earth, a histogram of the probabilistic Kp forecast is also provided.
