Prediction Detail

Prediction for CME (2018-08-19T07:36:00-CME-001)

CME Observed Time: 2018-08-19T07:36Z
CME Note: SIDC: In SoHO/LASCO C2 coronagraph images a very narrow (only around 10 degrees angular width) CME is visible from August 19 7:36UT onwards, directed towards the South-West. It is also visible from Stereo A COR2, also narrow and directed to the South-West from this viewpoint. The arrival time for this CME could have been confused with the arrival time of the 2018-08-20T21:24Z CME.
CME Shock Arrival Time: 2018-08-24T05:50Z
Observed Geomagnetic Storm Parameters due to CME:

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.
