## Alert Summary:
Type O CME detected by STEREO-B COR2.
Start time of the event: 2012-07-12T16:54Z (STEREO-B-COR2).
Based on rough estimates (only STEREO-B-COR2 images are available currently) the CME parameters are:
Estimated speed: ~1400 km/s.
Estimated opening half-angle: ~ 70 deg.
Direction (lon./lat.): -6/-17 in Heliocentric Earth Ecliptic coordinates.
The CME is associated with the X1.4 flare peaked at 2012-07-12T16:52Z (see alert 20120712-AL-001).
All spacecraft between the source region (AR 1520 - S15W01) and Earth (including MEO, GEO and other high-altitude orbits and high-inclination LEO) can be impacted. Updates on this event will be provided when available.
