[None, Passengers and crew in high-flying aircraft at high latitudes may be exposed to elevated radiation risk, Radiation hazard avoidance recommended for astronauts on EVA; passengers and crew in high-flying aircraft at high latitudes may be exposed to radiation risk, Unavoidable radiation hazard to astronauts on EVA; passengers and crew in high-flying aircraft at high latitudes may be exposed to radiation risk, Unavoidable high radiation hazard to astronauts on EVA (extra-vehicular activity); passengers and crew in high-flying aircraft at high latitudes may be exposed to radiation risk]
-
["None", "Infrequent single-event upsets possible", "Single-event upsets, noise in imaging systems, and slight reduction of efficiency in solar panel are likely", "May experience memory device problems and noise on imaging systems; star-tracker problems may cause orientation problems, and solar panel efficiency can be degraded", "Satellites may be rendered useless, memory impacts can cause loss of control, may cause serious noise in image data, star-trackers may be unable to locate sources; permanent damage to solar panels possible"]
-
["Minor impacts on HF radio in the polar regions", "Small effects on HF propagation through the polar regions and navigation at polar cap locations possibly affected", "Degraded HF radio propagation through the polar regions and navigation position errors likely", "Blackout of HF radio communications through the polar regions and increased navigation errors over several days are likely", "Complete blackout of HF (high frequency) communications possible through the polar regions, and position errors make navigation operations extremely difficult"]
-
[Minor, Moderate, Strong, Severe, Extreme]

[Is quiet, Minor radio blackout, Moderate radio blackout, Strong radio blackout, Severe radio blackout, Extreme radio blackout]
-
["Low-frequency navigation signals degraded for brief intervals", "Degradation of low-frequency navigation signals for tens of minutes", "Low-frequency navigation signals degraded for about an hour", "Outages of low-frequency navigation signals cause increased error in positioning for one to two hours. Minor disruptions of satellite navigation possible on the sunlit side of Earth", "Low-frequency navigation signals used by maritime and general aviation systems experience outages on the sunlit side of the Earth for many hours, causing loss in positioning. Increased satellite navigation errors in positioning for several hours on the sunlit side of Earth, which may spread into the night side"]
-
["Weak or minor degradation of HF radio communication on sunlit side, occasional loss of radio contact", "Limited blackout of HF radio communication on sunlit side, loss of radio contact for tens of minutes", "Wide area blackout of HF radio communication, loss of radio contact for about an hour on sunlit side of Earth", "HF radio communication blackout on most of the sunlit side of Earth for one to two hours. HF radio contact lost during this time", "Complete HF (high frequency) radio blackout on the entire sunlit side of the Earth lasting for a number of hours. This results in no HF radio contact with mariners and en route aviators in this sector"]
