Geomagnetic storm conditions are expected on Saturday night, likely pulling the northern lights further south below the Canadian border, according to a National Oceanic and Atmospheric Administration forecast.

The results of a massive solar flare from earlier this week could create more amazing light shows for people in the northern parts of the US.

Early attempts to capture images of the Northern Lights are going on show in a new exhibition at Cambridge's Polar Museum at the Scott Polar Research Institute. The sketches, by Danish-born teacher and self-taught scientist, Sophus Peter Tromholt (1851–1896) - were found by artist and archaeologist Dr Christine Finn.
