*Government Table Format Is In Descending Buy Of Severity ...

*Government table format is in descending purchase of severity*

NOAA Space Weather Scale for Geomagnetic Storms:

G5: Some power grid systems could experience complete collapse or blackouts. Pipeline currents can reach hundreds of amps. HF (high frequency) radio propagation may possibly be out of the question in many areas for days at a time. Satellite navigation might be degraded for days; low-frequency radio navigation can be out for hours. Auroras seen at low latitudes.

G4: Possible widespread power system voltage control problems; protective systems will mistakenly trip out key assets from the grid. HF radio propagation sporadic. Satellite navigation degraded for hours. Low-frequency radio navigation disrupted. Auroras seen at mid-to-low latitudes.

G3: Power system voltage corrections might be required; false alarms triggered on some protection devices. Intermittent satellite navigation and low-frequency radio navigation problems may possibly occur. HF radio may possibly be intermittent. Aurora has long been seen as mid-latitudes.

G2: High-latitude power systems may perhaps experience voltage alarms, long-duration storms may cause transformer damage. nike air max 2012 and nike air max shoes HF radio propagation can fade at higher latitudes. Auroras visible at high-to-mid-latitudes.

G1: Possible weak power grid fluctuations. Migratory animals affected. Auroras commonly visible at high latitudes.

NOAA Space Weather Scale for Solar Radiation Storms:

S5: Radiation risk in high-flying aircraft at high latitudes. Satellites may perhaps be rendered useless. Permanent damage to solar panels possible. Complete blackout of HF (high frequency) communications possible in polar regions. GPS/radio-navigation extremely unreliable.

S4: Radiation risk in high-flying aircraft at high latitudes. Degradation of satellite and solar panel efficiency. Blackout of HF radio communications through the polar regions. Increased GPS/radio-navigation errors.

S3: Radiation risk in high-flying aircraft at high latitudes. Sporadic satellite interference. Degradation of HF radio propagation in polar regions. GPS/radio-navigation errors likely.

S2: May be high-flying aircraft radiation risk at high latitudes. Infrequent satellite single-event upsets possible. Small effects on HF propagation and GPS/radio-navigation.

S1: No biological concerns. No satellite concerns. May perhaps be occasional HF radio static.

NOAA Space Weather Scale for Radio Blackouts:

R5: Complete HF (high frequency) radio blackout on sunlit side in the Earth for periods lasing several hours. GPS/radio-navigation outages planet-wide.

R4: HF communications blackout on most in the sunlit side of Earth for a person to two hours. Minor GPS/radio-navigation disruptions.

R3: Wide area blackout of HF communications for periods of approximately an hour on sunlit side of Earth. GPS/radio-navigation degradation.

R2: Limited HF blackouts. Limited GPS/radio-navigation degradation.

R1: Minor degradation of HF communications. Minor GPS/radio-navigation degradation for brief periods.
