Monitor solar storms, radio blackouts, geomagnetic activity and solar wind using NOAA Space Weather Prediction Center observations.
Kp 5 or higher indicates geomagnetic storm conditions. Observations are not a local aurora forecast.
Negative Bz combined with fast solar wind can increase geomagnetic activity.
G1–G5: Geomagnetic storms; can affect satellites, power systems and aurora visibility.
R1–R5: Radio blackouts caused by solar X-ray activity.
S1–S5: Solar radiation storms; important for aviation and spacecraft operations.
Kp: Global magnetic activity on a scale of 0 to 9.
