geomagnetic storm
Let an agent explain geomagnetic storms, relay causes, measurement, impacts and forecasting from space weather agency sources, describe substorms, and distinguish geomagnetic storms from solar flares, solar radiation storms, auroras as effects and weather on Earth, pointing people to official space weather alerts.
Research draft, second pass
A second pass drafted this model: the structure a model of this thing needs, and what is known about it in the world. The line under this one says how the second half was obtained - researched against sources, or recalled without web access, in which case nothing here was read anywhere and every claim is a lead to verify. Unreviewed either way.

Purpose and description
Let an agent explain geomagnetic storms, relay causes, measurement, impacts and forecasting from space weather agency sources, describe substorms, and distinguish geomagnetic storms from solar flares, solar radiation storms, auroras as effects and weather on Earth, pointing people to official space weather alerts.
A temporary disturbance of Earth s magnetosphere caused by solar wind shocks and coronal mass ejections, measured by indices such as Kp and Dst, which can produce vivid aurorae at lower latitudes, disrupt satellites, radio communications and GPS, and induce currents in power grids, as in the 1859 Carrington Event and the 1989 Quebec blackout; smaller magnetospheric substorms release stored energy and brighten aurorae. Space weather agencies issue alerts.
What it is for: Not applicable; a space weather phenomenon.
It can be explain causes and effects; relay measurement and forecasting; describe substorms; distinguish related phenomena.
Distinguishing features
Solar wind driven
Measured by indices
Technological impacts
Forecasted by agencies
What it looks like
Not a visible object as such; seen through aurorae.
Physical character
NOAA scale: G1 to G5 note
Carrington Event: 1859 year
Quebec blackout: March 1989 note
May 2024 storm: G5 note - widespread aurorae
How it is recognised
Disturbance of Earth s magnetosphere
Geomagnetic storm, substorm, G1 to G5 storms
Solar flares are bursts of radiation; radiation storms are energetic particles; aurorae are effects; Earth weather is atmospheric
