## Alert Summary:

Solar energetic particle event detected by STEREO B. The flux of 13-100 MeV protons exceeds 10^(-1) pfu/MeV starting at 2012-07-12T18:18Z.

Earlier solar energetic particle event was detected by GOES and SOHO (see alerts 20120712-AL-002, 20120712-AL-003).

The enhancement is associated with the X1.4 flare peaked at 2012-07-12T16:52Z (see alert 20120712-AL-001) and its associated CME.

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.

Activity ID: 2012-07-12T17:50:00-SEP-001.
