Prediction Detail

Prediction for CME (2018-07-05T04:39:00-CME-001)

CME Observed Time: 2018-07-05T04:39Z
CME Note: This CME is visible in STEREO A COR2 on the W limb. It starts as a slowly brightening near the streamer before the CME is clearly visible. For this reason the start time can be anywhere between 02:39 (labelled by SIDC) and 13:09 (labelled by SWPC).
CME Shock Arrival Time: 2018-07-10T11:25Z
Observed Geomagnetic Storm Parameters due to CME:

Predicted Arrival Time: 2018-07-07T10:00Z
Confidence that the CME will arrive: 2.0%
Predicted Dst min. in nT: -41
Predicted Dst min. time: 2018-07-07T22:00Z
Prediction Method: Other
Prediction Method Note:
NOAA G2 event using a solar wind velocity = 750 km/s and the ENLIL+Rice Dst algorithm
Lead Time: 108.82 hour(s)
Difference: 73.42 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.
