WARNING: Proton 100MeV Integral Flux above 1pfu expected
Valid From: 2014 Apr 18 1412 UTC
Valid To: 2014 Apr 18 2100 UTC
Warning Condition: Onset
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.
