NOAA Space Weather Scales - NOAA / NWS Space Weather …
WEBThe scales describe the environmental disturbances for three event types: geomagnetic storms, solar radiation storms, and radio blackouts. The scales have numbered levels, analogous to hurricanes, tornadoes, and earthquakes that convey severity. They list possible effects at each level.
These are the 5 categories that measure geomagnetic storms
WEBOct 29, 2021 · NOAA has developed a 5-level scale, ranging from G1 to G5, to rate any incoming geomagnetic activity, giving a crucial way to quantify the expected impacts.
Geomagnetic storm - Wikipedia
WEBA-index. The G-scale used by the U.S. National Oceanic and Atmospheric Administration, which rates the storm from G1 to G5 (i.e. G1, G2, G3, G4, G5 in order), where G1 is the weakest storm classification (corresponding to a Kp value of 5), and G5 is the strongest (corresponding to a Kp value of 9).
WEBSpacecraft operations: corrective actions to orientation may be required by ground control; possible changes in drag affect orbit predictions. Other systems: HF radio propagation can fade at higher latitudes, and aurora has been seen as low as New York and Idaho (typically 55° geomagnetic lat.).**. Kp=6.
SANSA Space Weather - Geomagnetic Storm Scale
WEBThe NOAA Geomagnetic Storm Scale indicates the severity of geomagnetic storms. It is denoted by a G followed by a number from 1 to 5, with 1 being a minor event, and 5 being an extreme event. The scale uses the planetary K-Index, K p as it's physical measure, the scale levels are shown below:
K-index - Wikipedia
WEBThe K-scale is a quasi-logarithmic scale derived from the maximum fluctuation R (in units of nano teslas, nT) in the horizontal component of Earth's magnetic field observed on a magnetometer relative to a quiet day during a three-hour interval.

WEBOct 25, 2021 · In an effort to convey the threat level to the public, NOAA rates geomagnetic storms on a scale from G1 to G5, similarly to how hurricanes are rated from category one to five on the...

WEBThis index is the basis for one of the three NOAA Space Weather Scales, the Geomagnetic Storm, or G-Scale, that is used to describe space weather that can disrupt systems on Earth.
Geomagnetic Storms Information - space weather
WEBSpace Weather Scale for Geomagnetic Storms. Power systems: weak power grid fluctuations can occur. Spacecraft operations: minor impact on satellite operations possible. Other systems: migratory animals are affected at this and higher levels; aurora is commonly visible at high latitudes (northern Michigan and Maine)**.
