- The northern lights forecast typically provides information on the expected aurora activity level. Higher values indicate stronger geomagnetic storms and a greater likelihood of visible northern lights at lower latitudes. Northern lights forecasts are given for three days and are consistently updated.

Jan 9, 2024 · In the Northern Lights forecast, there are three main indicators for tracking the Aurora: Kp Index. Ovation Auroral. Solar Rotation. KP Index in Northern Lights forecast. The KP index is the most common way to forecast the Northern Lights, and you can use it both for short-term and long-term Aurora prediction.

Aurorais the name given to the glow or light produced when electrons from space flow down Earth’s magnetic field and collide with atoms and molecules of the upper atmosphere in a ring or oval centered on the magnetic pole of Earth. The collisions produce light much like how electrons flowing through gas in a neon light collide with neon and other g...
The aurora is formed from interactions between the solar wind streaming out from the sun and Earth’s protective magnetic field, or magnetosphere. The aurora is one manifestation of geomagnetic activity or geomagnetic storms. As the solar wind increases in speed and theinterplanetary magnetic fieldembedded in the solar wind turns southward, the geom...
The aurora is one manifestation of geomagnetic activity. The electrons that create the aurora also carry electric currents that are conducted through the ionized portion of the upper atmosphere (the ionosphere). These currents generate perturbations or changes in the magnetic field at the surface of Earth. The changes in the apparent magnetic field...
The different colors of the aurora are produced when different atmospheric atoms and molecules are excited to various energy levels. The most common auroral color is a pale green color at a wavelength of 557.7 nm. This is the result of atomic oxygen having been excited to the 1S, or singlet S, state. Another less common color is a deep red which is...
The Aurora Borealis and Aurora Australis are mirror images of each other. When the aurora becomes active in one hemisphere, it will become active in the other at the same time. Auroral activity, as measured by brightness, complexity of the formations, and location, is directly correlated with geomagnetic activity. Aurora exists nearly all the time....
This page provides a prediction of the aurora’s visibility tonight and tomorrow night in the charts below. The animations further down show what the aurora’s been up to over the last 24 hours and estimates what the next 30 minutes will be like.
Auroras can still be spotted south of about 50° latitude during the summer. Statistically, the equinox months of September and March are best for aurora activity. The winter months of October-thru-February are also good (there is definitely no shortage of darkness!).
Generally, the most popular website for checking the aurora borealis forecast in the northern hemisphere is National Oceanic and Atmospheric Administration (NOAA). In the southern hemisphere, head to the Bureau of Meteorology (BOM). The most important value when reading the forecast is the Kp Index.
