aurora
Let an agent explain auroras and their physics, describe where and when they can be seen and how they are forecast, support observation and photography, and describe cultural and scientific significance.
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 auroras and their physics, describe where and when they can be seen and how they are forecast, support observation and photography, and describe cultural and scientific significance.
A natural display of light in the sky at high latitudes, the aurora borealis in the north and aurora australis in the south, produced when charged particles from the solar wind, guided by the Earth magnetic field, excite atoms and molecules in the upper atmosphere, producing curtains, arcs and rays of green, red and purple light; auroras are studied in space physics, are forecast from solar activity, and attract observers and tourists.
What it is for: Polar light displays.
It can be explain physics; describe viewing and forecasting; support observation; describe significance.
Distinguishing features
Solar wind driven
Magnetic field guided
Colour by gas and altitude
Polar ovals
What it looks like
Curtains and arcs of coloured light in the night sky.
How it is recognised
Light from excited atmospheric gases
High latitudes, driven by solar activity
Airglow is faint and uniform; noctilucent clouds are ice clouds
