Issue Time: 2013 May 22 1503 UTC
ALERT: Proton Event 100MeV Integral Flux exceeded 1pfu
Begin Time: 2013 May 22 1455 UTC
Potential Impacts: An enhancement in the energetic portion of the solar radiation spectrum may indicate increased biological risk to astronauts or passengers and crew in high latitude, high altitude flights. Additionally, energetic particles may represent an increased risk to all satellite systems susceptible to single event effects. This information should be used in conjunction with the current Solar Radiation Storm conditions when assessing overall impact.
