CME Scoreboard: Prediction Detail

Prediction for CME (2017-09-10T16:00:00-CME-001)

CME Observed Time: 2017-09-10T16:00Z
CME Note: Associated with X8.2 flare from AR 12673. Arrival at of CME-associated disturbance DSCOVR has no clear flux-rope signature, shock only.
CME Shock Arrival Time: 2017-09-12T19:26Z
Observed Geomagnetic Storm Parameters due to CME:
Max Kp: 5.0
Dst min. in nT: -50
Dst min. time: 2017-09-13T01:00Z

Predicted Arrival Time: 2017-09-12T07:00Z (-12.0h, +12.0h)
Confidence that the CME will arrive: 60.0%
Predicted geomagnetic storm max Kp range due to CME: 5.0 - 7.0
Prediction Method: WSA-ENLIL + Cone (Met Office)
Prediction Method Note:

Met Office ENLIL settings.
ENLIL version: 2.7
Resolution: medium-res (512x60x180) (X1=0.1-1.7/uniform X2=30.-150./uniform X3=0.-360./uniform)
Ambient settings: a3b2-sa1
WSA version: 2.2

Please specify following CME input parameters.
Time at 21.5Rs boundary: 10/1800 UTC
Radial velocity (km/s): 2000 km/s
Longitude (deg): 70W
Latitude (deg): 9S
Half-angular width (deg): 75 deg

Notes: This CME is hard to model and get a good fit, so there is low confidence in timing. Our ENLIL model suggests arrival of 12/0200 UTC, but the forecast is at present 12/0700 UTC, with a wide margin of error of +/- 12 hours.

CCMC Rules of the Road: CCMC requests that users notify the CCMC, CME model/technique developers and submitting forecasters/researchers before performing event and validation studies with data from the CME Arrival Time Scoreboard. It is recommended that such studies be performed with the knowledge and collaboration of developers and submitting forecasters/researchers.
