Prediction Detail

Prediction for CME (2019-05-12T19:54:00-CME-001)

CME Observed Time: 2019-05-12T19:54Z
CME Note: There is no clear signature arrival for this specific CME. The arrival attributed to the 2019-05-13T16:09Z CME is also very weak and difficult to be certain about it.
CME was not detected at Earth.
Observed Geomagnetic Storm Parameters due to CME:
----

Predicted Arrival Time: 2019-05-16T10:00Z (-9.0h, +9.0h)
Confidence that the CME will arrive: 40.0%
Predicted geomagnetic storm max Kp range due to CME: 3.0 - 5.0
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: 2019-05-13T03:30Z
Radial velocity (km/s): 480 km/s
Longitude (deg): 13E
Latitude (deg): 14S
Half-angular width (deg): 30 deg

Notes: Difficult to analyse with the CAT tool output sensitive to longitude and half angle. Estimated speeds varied between 400 and 600 km/s, but settled approximately on the mean. The Ensemble suggests an error margin of approx plus or minus 9 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.
