What is Aurora Alert?

Aurora Alert is the website which delivers aurora forecast and the current sky images of areas in the auroral belt. This website is operated by the Space Environment Laboratory, Applied Electromagnetic Research Institute in the National Institute of Information and Communications Technology.
The “Simulated Distribution” is created by using calculation results of a real-time global magnetosphere simulation driven by the real-time solar wind data acquired by DSCOVR. The real-time magnetosphere simulation is operated on the high-speed computing system at NICT. (Due to the limitation of the current real-time simulator, auroral data cannot be obtained at latitudes lower than the latitude of about 60 degrees in the geomagnetic coordinate system. This limit latitude may be seen as boundaries, when, for example, the aurora is very active.)
The aurora forecast has been calculated automatically based on Aurora Electrojet (AE) index and the real-time data of solar wind by DSCOVR. Aurora images are taken by live cameras installed in Alaska and Syowa Station.
