Prediction for CME (2018-02-12T01:25:00-CME-001)

CME Observed Time: 2018-02-12T01:25Z
CME Note: This partial halo CME is associated with a long duration C1.5 flare peaking at 1:35Z from AR2699.
CME Shock Arrival Time: 2018-02-15T07:38Z
Observed Geomagnetic Storm Parameters due to CME:

Predicted Arrival Time: 2018-02-15T16:30Z (-6.0h, +6.0h)
Confidence that the CME will arrive: 70.0%
Prediction Method: DBM
Prediction Method Note:
Model & CME input parameters:

CME take-off date & UTC time: Feb 12, 2018 at 05UT
? = 0.3010-7 km-1, w = 350 km/s,
R0 = 15 rSun, v0 = 600 km/s, ? = 20, ?CME = 15
Rtarget = 0.99 AU, ?target = 0 

Comment: the CME was directed towards South - maybe a flank hit with prolonged geomagnetic effects.
Lead Time: 63.13 hour(s)
Difference: -8.87 hour(s)

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.
