## Summary:

BETA PRODUCT. ENSEMBLE PRODUCT IS STILL IN DEVELOPMENT MODE. PLEASE LET US KNOW IF YOU HAVE ANY SUGGESTIONS FOR MODIFICATIONS.  

Ensemble modeling update on CME with ID 2023-03-12T19:24:00-CME-001 (see previous notification 20230313-AL-006). Based on analysis by the Moon to Mars Space Weather Analysis Office and heliospheric ensemble modeling carried out at the Community Coordinated Modeling Center, it is estimated that the CME may impact STEREO A. For 24 ensemble members (see notes section), simulations indicate that the leading edge of the CME will reach:

- STEREO A between about 2023-03-14T22:26Z and 2023-03-15T14:16Z (average arrival 2023-03-15T08:23Z) for 66% of simulations.

Additionally the CME is estimated to reach NASA missions near Earth between about 2023-03-14T23:20Z and 2023-03-15T15:49Z (average arrival 2023-03-15T08:55Z) for 70% of simulations.  The ensemble-based forecast indicates that there is a 79% chance for the maximum Kp index to be in the 4-6 range (below minor to moderate).

## Notes:
This CME event is also predicted to have an impact at Solar Orbiter at 2023-03-14T11:00Z (plus minus 7 hours) based on previous heliospheric modeling (see notification 20230313-AL-006).

Ensemble CME modeling at M2M 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.
