CME Scoreboard

Prediction for CME (2015-06-21T02:48:00-CME-001)

Ensemble modeling estimates the spread/uncertainty in CME arrival time predictions using the WSA-ENLIL+Cone model due to uncertainties in CME input parameters.  This is achieved by measuring N CME input parameters, then performing an ensemble of N runs of WSA-ENLIL cone model.  This gives an ensemble of N CME arrival times and impact estimates.

## 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(s) with ID(s) 2015-06-21T02:48:00-CME-001 (see previous notification 20150621-AL-001). Based on heliospheric ensemble modeling carried out at NASA GSFC Space Weather Research Center, it is estimated that the CME may impact Spitzer. For 32 ensemble members (see notes section), simulations indicate that the leading edge of the CME will reach:

- Spitzer between about 2015-06-23T09:21Z and 2015-06-23T13:19Z (average arrival 2015-06-23T11:20Z) for 6% of simulations.

Additionally the CME is estimated to reach NASA missions near Earth between about 2015-06-22T13:54Z and 2015-06-23T02:23Z (average arrival 2015-06-22T19:03Z) for 100% of simulations.  The ensemble-based forecast indicates that there is a 44% chance for the maximum Kp index to be in the 7-8 range (strong to severe).

## 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.
