NOAA Geomagnetic Activity Observation and Forecast

NOAA Geomagnetic Activity Observation

NOAA's Geomagnetic Activity Observation and Forecast service provides real-time and forecast information on geomagnetic activity, which can affect power grids, communications, and navigation systems. The service uses a variety of data sources, including ground-based magnetometers, satellite measurements, and solar wind observations, to provide accurate and timely information.

Forecast Information

The service provides forecast information on geomagnetic activity for the next 24 hours and up to 30 days in advance. The forecast information includes the expected Kp index, which is a measure of the strength of geomagnetic activity. The Kp index ranges from 0 to 9, with higher values indicating stronger geomagnetic activity.

The service also provides information on the expected occurrence of geomagnetic storms, which are sudden and intense increases in geomagnetic activity. Geomagnetic storms can cause damage to power grids, communications, and navigation systems. The service provides advance warning of geomagnetic storms, allowing users to take steps to mitigate their effects.
