This is a short-term forecast of the location and intensity of the aurora. 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.
An aurora (pl. aurorae or auroras), also commonly known as the northern lights (aurora borealis) or southern lights (aurora australis), is a natural light display in Earth's sky, predominantly seen in high-latitude regions (around the Arctic and Antarctic).
9 de feb. de 2024 · The northern lights are created when energized particles from the sun slam into Earth's upper atmosphere at speeds of up to 45 million mph (72 million kph), but our planet's magnetic field...
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.)
16 de feb. de 2017 · February 16, 2017. • 9 min read. The otherworldly aurora borealis, or northern lights, begin high in the Earth’s atmosphere—at altitudes from 60 to more than 250 miles—when charged particles from...
The northern lights most commonly occur within the geographic area beneath the auroral oval. It encompasses latitudes between 60 and 75 degrees and takes in Iceland, northern parts of Sweden, Finland, Norway, Russia, Canada and Alaska as well as southern Greenland.
It also shows a 'viewline' that represents the southern-most locations from which you may see the aurora on the northern horizon.This product is based on the OVATION model and uses the maximum forecast geomagnetic activity (Kp) between 6pm and 6am US Central Time.
