Northern lights: when and how to see them
What causes auroras, live activity forecasts from NOAA and SpaceWeatherLive, geomagnetic storms and twilight times – what you need not to miss them.
The Sun is near the peak of its cycle, so auroras now reach far further south than usual. NOAA’s aurora dashboard and SpaceWeatherLive show the forecast live, and the twilight time where you are tells you when to start looking. Add Wikipedia on auroras and geomagnetic storms and NASA’s astronomy picture of the day.

Wikipedia AuroraAn aurora is a natural light display in Earth's upper atmosphere caused by charged particles from the Sun colliding with atoms in the atmosphere. These collisions excite oxygen and nitrogen, which then emit light of different colours such as green, red, and purple. When observed in high-latitude re… https://en.wikipedia.org/wiki/Aurora | |

Wikipedia Geomagnetic stormA geomagnetic storm, also known as a magnetic storm, is a temporary disturbance of the Earth's magnetosphere that is driven by interactions between the magnetosphere and large-scale transient plasma and magnetic field structures that originate on or near the Sun. https://en.wikipedia.org/wiki/Geomagnetic_storm | |
