A fantastic show of Northern Lights could be seen across the UK and gave Sussex residents a real treat – you can see our countywide picture gallery here.
And our readers posted their pictures on the Crawley Observer Facebook page – and here is a selection of those pictures.
The Northern Lights – or aurora borealis – appear as bright, swirling curtains of lights in the night sky and range in colour from green to pink and scarlet. The phenomena is chiefly influenced by geomagnetic storms, of which the Met Office said there was a "severe" one due to reach Earth overnight on 10 October.
