Planet Earth Aurora Forecast | NOAA Space Weather Prediction Center

Planet Earth Aurora Forecast | NOAA Space Weather Prediction Center

Northern Hemisphere
Southern Hemisphere

This is a short-term forecast of the location and intensity of the aurora. The two maps show the North and South poles of Earth respectively. The brightness and location of the aurora is typically shown as a green oval centered on Earth’s magnetic pole. The green ovals turn red when the aurora is forecasted to be more intense. The sunlit side of Earth is indicated by the lighter blue of the ocean and the lighter color of the continents. Aurora can often be observed somewhere on Earth from just after sunset or just before sunrise. The aurora is not visible during daylight hours. The aurora does not need to be directly overhead but can be observed from as much as a 1000 km away when the aurora is bright and if conditions are right. 

The aurora is an indicator of the current geomagnetic storm conditions and provides situational awareness for a number of technologies.  The aurora directly impacts HF radio communication and GPS/GNSS satellite navigation.  It is closely related to the ground induce currents that impact electric power transition.

For many people, the aurora is a beautiful nighttime phenomenon that is worth traveling to arctic regions just to observe. It is the only way for most people to actually experience space weather. 

Earth auroras have different names depending on which pole they occur at. Aurora Borealis, or the northern lights, is the name given to auroras around the north pole and Aurora Australis, or the southern lights, is the name given for auroras around the south pole.

To see how such space weather may affect Earth, please visit NOAA’s Space Weather Prediction Center, the U.S. government’s official source for space weather forecasts, watches, warnings, and alerts. 

Geomagnetic storms involve powerful bursts of energy. Flares and solar eruptions can impact radio communications, electric power grids, navigation signals, and pose risks to spacecraft, including satellites and astronauts.

NASA works as a research arm of the nation’s space weather effort. NASA observes the Sun and our space environment constantly with a fleet of spacecraft that study everything from the Sun’s activity to the solar atmosphere, and to the particles and magnetic fields in the space surrounding Earth.
