## Summary:

Update on CME with ID 2017-09-10T16:09:00-CME-001 (see previous notification 20170910-AL-006).  Based on preliminary heliospheric modeling carried out at NASA GSFC Space Weather Research Center, it is estimated that this CME may affect STEREO B.  The leading edge of the CME will reach STEREO B at 2017-09-12T05:12Z (plus minus 7 hours). 

The simulation also indicates that the CME may 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 2017-09-13T02:00Z (plus minus 7 hours). 
   

Updated CME parameters are:

Start time of the event: 2017-09-10T16:09Z.

Estimated speed: ~1670 km/s.

Estimated opening half-angle: 63 deg.

Direction (lon./lat.): 83/-8 in Heliocentric Earth Equatorial coordinates.

Activity ID: 2017-09-10T16:09:00-CME-001
