This product is based on the OVATION model and provides a 30 to 90 minute forecast of the location and intensity of the aurora. The forecast lead time is the time it takes for the solar wind to travel from the L1 observation point to Earth. The two maps show the North and South poles of Earth respectively. The brightness and location of the ...

Aurora. An aurora[ a] ( pl. aurorae or auroras ), [ b] also commonly known as the northern lights ( aurora borealis) or southern lights ( aurora australis ), [ c] is a natural light display in Earth 's sky, predominantly seen in high-latitude regions (around the Arctic and Antarctic ).
The Aurora Borealis (Northern Lights) and Aurora Australis (Southern Lights) are the result of electrons colliding with the upper reaches of Earth’s atmosphere. (Protons cause faint and diffuse aurora, usually not easily visible to the human eye.) The electrons are energized through acceleration processes in the downwind tail (night side) of ...
