Prediction for CME (2013-08-21T05:24:00-CME-001)

Subject: Space Weather Alert - CME
## NASA Goddard Space Flight Center, Space Weather Research Center ( SWRC )
## Message Type: Space Weather Alert - CME

## Message Issue Date: 2013-08-21T17:12:00Z
## Message ID: 20130821-AL-002
##Summary:
C-type CME detected by STEREO-A/COR2, STEREO-B/COR2, SOHO LASCO C2
and C3.
Start time of the event: 2013-08-07T18:36Z.
Estimated speed: ~610 km/s.
Estimated opening half-angle: 40 deg.
Direction (lon./lat.): -2/10 in Heliocentric Earth Ecliptic coordinates.
Activity ID: 2013-08-21T05:24:00-CME-001.
Based on preliminary heliospheric modeling carried out at NASA GSFC
Space Weather Research Center, it is estimated that the CME may
have a small impact on Earth. Simulations indicate that the
leading edge of the CME will reach Earth at about 2013-08-23T23:59Z
(plus minus 7 hours). The roughly estimated expected range of the
maximum Kp index is 4-6 (minor-moderate).
Due to lack of good imaging data the above parameters are
rough estimates.
