Explore aurora using keograms

Over 1000 night of aurora activity are featured here as "Keograms", each a visualization of the sky overhead from sunset to sunrise. A keogram helps you find nights of strong aurora activity. Here are some examples:

Aurora moving overhead from the north
Auroral substorm fills the sky
Less common red aurora!
Obscuring clouds forming
Bright moon in the south
Aurora at dawn

Compare them to geomagnetic conditions

Below each keogram is coloured bar showing the Kp-index - a measure of geomagnetic activity throughout the night, updated every 3 hours. Higher Kp means greater the chance of seeing the aurora.
