Prediction for CME (2013-09-29T22:40:00-CME-001)

## NASA Goddard Space Flight Center, Space Weather Research Center ( SWRC )
## Message Type: Space Weather Alert - CME
##
## Message Issue Date: 2013-09-30T03:32:00Z
## Message ID: 20130930-AL-001
##Summary:
C-type CME detected by STEREO-B COR2 / SOHO LASCO C3.
Start time of the event: 2013-09-29T22:40Z.
Estimated speed: ~850 km/s.
Estimated opening half-angle: 50 deg.
Direction (lon./lat.): 30/20 in Heliocentric Earth Equatorial coordinates.
Activity ID: 2013-09-29T20:39:00-CME-001.
Note that the CME parameters are very rough estimates based on STEREO-B data only due to gaps in STEREO-A and SOHO coverage.
Based on preliminary heliospheric modeling carried out at NASA GSFC Space Weather Research Center, it is estimated that the CME may impact Earth and Juno. Simulations indicate that the leading edge of the CME will reach Earth and Juno at about 2013-10-02T14:39Z (plus minus 7 hours). The roughly estimated expected range of the maximum Kp index is 3-5 (below minor to minor). Updates on this event will be provided when available.

## Notes:
This CME is related to a large prominence eruption extending about 40 degrees observed after 2013-09-29T21:00Z in the northwest quadrant of the Earth-facing solar disk.
