## Summary:

S-type CME detected by STEREO A / SOHO. 

Start time of the event: 2017-05-23T05:00Z.

Estimated speed: ~375 km/s.

Estimated opening half-angle: 26 deg.

Direction (lon./lat.): 12/-7 in Heliocentric Earth Equatorial coordinates (see [1] in Notes).

Activity ID: 2017-05-23T05:00:00-CME-001


Based on preliminary heliospheric modeling carried out at NASA GSFC Space Weather Research Center, it is estimated that this CME will have a glancing blow at NASA missions near Earth. Simulations indicate that the flank of the CME will reach NASA missions near Earth at about 2017-05-26T18:00Z (plus minus 7 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.
