Prediction Detail

Prediction for CME (2019-05-13T16:09:00-CME-001)

CME Observed Time: 2019-05-13T16:09Z
CME Note: Signature is very weak and difficult to discern exact time. From Teresa Nieves-Chinchilla: Around ~21 hrs on the May 16, there is a monotonic change in the magnetic field direction that can be associated with a flux rope signature.
CME Shock Arrival Time: 2019-05-16T16:10Z
Observed Geomagnetic Storm Parameters due to CME:
Max Kp: 3.0

Predicted Arrival Time: 2019-05-19T00:00Z
Predicted geomagnetic storm max Kp range due to CME: 7.0 - 7.0
Predicted Dst min. in nT: -66
Predicted Dst min. time: 2019-05-19T06:00Z
Prediction Method: Anemomilos
Prediction Method Note:
Two events created from extended flare/CME at 201905131600 from N02W06 event. NOAA G3 scale and combined DST -66 nT predicted. Two flux ropes predicted that merge, one with 517 km/s and one with 352 km/s
Lead Time: 24.92 hour(s)
Difference: -55.83 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.
